I am a newbee in this area. So please pardon me if I am not speaking the language of the technology.
In our company, I am trying configure a VPN connection. We had a DSL connection which was running through AVM FritzBox 7490.
I have modified the Fritzbox to be used as bridge (please correct me if I am wrong) and enabled PPPoE. The ASA 5505 router is behind the Fritzbox now with PPPoE as the outside interface. Everything is working fine with the network.
My next task is to configure a VPN connection so that people from other sites are able to connect to the network at our site. I could set it up as IPSec Remote Access Wizard and it is also working.
But there is one problem: The Public IP of the VPN Server (ASA device) is changing continuously. That means, each time someone wants to access VPN should ask me the current public IP and login. I tried the to make Public IP fixed (with one of the IP that ASA was holding at that time) but it returned an error. Also it was asking for Subnet Mask 255.255.255.255 which was not aveilable in the list.
Is there anyway that I can control the Public IP? Or am I making a mistake somewhere? I tried searching in the web, but could not find a solution. Can you please help me?
Thanks in advance!
