I'm looking for elegant solution to migrate VPN Clients to new public IP.
I have PIXs (public IP x.x.x.1) and Concentrator (x.x.x.2) to be replaced with ASA. All VPN Clients (~200 users) preconfigured with x.x.x.2.
What is the best way (minimum impact) to âcombineâ PIX and Concentrator in this case?
I see couple options here:
1. reconfig clients with new IP (manually or to push new config);
2. Config x.x.x.2 on ASA, but I do not think it's possible to have IPs from same network on different interfaces;
3. Is there âforward IP to IPâ option?
4. Have ASA and Concentrator running and to reconfig end users manually
5. Subnet public network.
What do you think?
