zhendongzhang · ‎03-14-2007

Situation:

1.There is a ADSL with dynamic public ip address and connect to router(cisco2811).So each time as router reboot will change pulic ip address.I need to access internet and connect to vpn concentrator by CISCO VPN client from internal computer.

2. Internal IP address scope :10.35.186.10/255.255.255.0

Question:

1.How to configure Dynamic NAT on ADSL with Dynamic IP address? Once router reboot don't need do any other configure.

2. And also allow internal computer connect to VPN concentrator by cisco vpn client.

Very appreciate if you may give me some informaton and configure example.

For your ip nat command you can specify an interface, in lieu of IP address, as a global translated address.

Thanks.

Thanks your information.

If my understanding is right,Specify an interface is PAT. Due to our VPN client need use the NAT.

Here is our VPN client connection entry information,I am don't sure PAT that's ok?
