Embodiment
At present a lot of mobile operator can provide custom-made mobile phone to the user, and the user uses custom-made mobile phone can remove the work of manual access configuration from, and operator pays the user by mobile phone after can in custom-made mobile phone, above-mentioned access configuration being set and uses.Yet in fact have many consumers and do not use the carrier customization mobile phone, especially some Continental Area users may go abroad or Hong Kong, Macao and Taiwan has been purchased mobile phone while playing, the Information Mobile Service that then at Continental Area, uses mobile operator to provide.The access configuration of acquiescence has probably been arranged on this mobile phone, but these acquiescence access configurations are obviously incorrect.Such as, when if the user uses the service of China Mobile, the Agent IP address 10.0.0.172 of the Agent IP address Bu Shi China Mobile in its acquiescence access configuration, but the Agent IP address of external or the regional operator in Hong Kong, Macao and Taiwan, as 10.30.3.151,172.24.128.36,192.168.99.2 etc.
The knowledgeable user of subnetwork can revise wrong Agent IP address in the access configuration voluntarily, be unaware of such problem but still have many consumers, it may suspect that fault has appearred in network, and even some user can constantly complain the network service quality of operator.In order to address the above problem, can use a kind of way of simple possible, by keeper's manual configuration NAT Server(network address translation services device) method by these address transition 10.0.0.172, realize the address error correction.Yet such mode is the problem of a headache for the keeper, it may need constantly manually to add item by item the Agent IP address of various mistakes.
The invention provides a kind of more easy-to-use solution and solve the problems referred to above.Please refer to Fig. 1 and Fig. 2, be embodied as example with software, a kind of preferred embodiment in, the invention provides a kind of Terminal Service device, its network equipment (the normally gateway device of mobile terminal) be applied between mobile terminal and operator's acting server is upper, other business hardware that this network equipment comprises CPU, internal memory, nonvolatile memory and comprises forwarding chip.CPU can this is corresponding computer program loads form this Terminal Service device to operation in internal memory.At logic level, this device comprises: configuration process unit, coupling performance element and modification unit, address.Please refer to Fig. 3, carry out following method in this device running:
Step 101, configuration process unit receiving management person issues the conversion acl rule and preserves by management channels, wherein this conversion acl rule be used for by the purpose IP address of keeper's appointment belong to specify the network segment the IP packet filtering out;
Step 102, the coupling performance element filters out the IP message of this conversion acl rule of coupling;
Step 103, address conversioning unit, by the purpose IP address of this IP message and corresponding IP address and the port that is converted to the acting server of appointment of destination interface, then sends to this acting server by this amended IP message.
Please refer to table 1, if adopt previously mentioned simple process mode, the keeper need to be issued to the combination of IP address and port in a list item of conversion configurations table by the function of configuration process unit.The coupling converting unit can first remove to check this conversion configurations table when the process IP message, and the mode of inspection is, if the purpose IP address of this IP message and destination interface match any list item, so just this IP message is submitted to address conversioning unit and is processed.The problem of this mode is, the combination of configuration of IP address and port may cause list item very huge one by one.The angle of using from reality, in the time of list item much tens and even hundreds of, the keeper is very difficult clearly recognizes in the conversion configurations table combination that has configured on earth which IP address and port, and the keeper checks that the conversion configurations table is all to need to spend a lot of time carefully to check each time.
| The IP address | Port |
| IP1 | P1 |
| IP2 | P2 |
| …… | …… |
| IP100 | P100 |
| …… | …… |
| IPn | Pn |
Table 1
And in the present invention, conversion can be specified the concrete network segment in acl rule, so in up to a hundred list items, the IP address can be combined as a few network segment simply.The inventor finds by a large amount of statistical analyses, in current customer mobile terminal more than 95%, the IP address of the acting server of configuration all concentrates in 10.0.0.0/8,172.16.0.0/16 and these three network segments of 192.168.0.0/16, that is to say, based on statistical analysis, find that carrying out polymerization by the network segment coordinates streamlining management person's the work dramatically of ACL mode again.For instance, keeper's configuration can be simplified following exemplary ACL configuration:
[NAT-acl-adv-3000]rule?permit?ip?destination?10.0.0.00.0.0.255
[NAT-acl-adv-3000]rule?permit?ip?destination?172.16.0.00.0.255.255
[NAT-acl-adv-3000]rule?permit?ip?destination?192.168.0.00.0.255.255
[NAT-GigabitEthernet0/0]nat?server?protocol?tcp?global?3000?inside?10.0.0.172?www
In above-mentioned several configurations, first three is that to indicate the IP address of which network segment be to need to revise, and the last item is the mode that shows concrete modification.Secondly by implementation of the present invention, keeper's configuration effort is simplified greatly, and, when the keeper finds to check the ACL that it configured, because configuration information is very brief, it can recognize the configuration of having carried out rapidly.When the keeper recognizes the default proxy server ip address of the mistake that appearance on some terminal is new, it may not need to carry out new configuration, because the default proxy server ip address of the mistake that this is new may have been covered by above-mentioned three network segments, the keeper even can rely on memory just to know this point like a cork.
It should be noted that, in the present invention, do not need the keeper to carry out any configuration to port, once the purpose IP matching addresses of an IP message is to above-mentioned conversion acl rule, this message is obviously the mobile terminal from a wrong access configuration so, at least its default proxy server ip address is wrong, and whether mistake does not need to be concerned about port.After this IP message is filtered out, address conversioning unit can be revised as the purpose IP address of message and port unification IP address and the port of appointment,
Without being concerned about that the unmodified front port of IP message is correct or wrong, anyway revise purpose IP address and the port of later IP message, be correct certainly, such as purpose IP address is modified to 10.0.0.172 and port is modified to 80.
On the basis of above-mentioned execution mode, the present invention can also carry out compatibility with prior art, described coupling performance element can priority check conversion configurations table, if the purpose IP address of IP message and port do not mate any one list item, continues so the processing of step 102.That is to say that conventional needle is more preferential to the inspection of single ip address and port combination.Because having the list item of only a few just to change acl rule in the list item that the keeper configures on the network equipment can't cover, therefore in order to take full advantage of the passing achievement of keeper, can the existing conversion configurations table of priority check, coupling does not continue to check whether the conversion acl rule mates again.
On the basis of above-mentioned execution mode, the present invention can also further do safe handling.If the combination of the purpose IP address of an IP message and port is correct, such as be 10.0.0.172 and 80, this IP message obviously can directly be let pass.But suppose that the purpose IP address of IP message and the combination of port are 10.0.0.172 and 8085, this is likely that wrong access configuration causes, in one embodiment, can pass off, after by the conversion acl rule, it being filtered out, by address conversioning unit, it is revised as to correct IP address and the combination of port.But now because the IP address is correct, port is wrong, it is likely also the attack message that the assailant sends, such as the assailant will send a plurality of purpose IP address when wanting to carry out vulnerability scanning, be correct acting server IP address, and port is a plurality of messages that change.
Because the acting server of mobile operator is the public service that is exposed to all users, therefore in order to improve the fail safe of this server, the keeper can issue a security acl rule, this security acl rule can be changed acl rule with respect to other and preferentially mates, target is to find out the IP address right but the IP message of port error, and the coupling performance element can out be submitted to the re-orientation processes unit by such IP packet filtering and be processed.The re-orientation processes unit can be by the server of this IP message redirecting to an appointment, sent message user's behavior by this server analysis, if find that the behavior is attack, server can notify other preposition safety means such as intrusion detection by this user add in blacklist, thereby effectively for acting server, provide security protection.
The foregoing is only preferred embodiment of the present invention, in order to limit the present invention, within the spirit and principles in the present invention not all, any modification of making, be equal to replacement, improvement etc., within all should being included in the scope of protection of the invention.
