Hey all,
I got something that I can't quite figure out...
Got a Pix setup to do VPN, 6.2(2). Inside is 192.168.10.x, VPN pool is 192.168.11.x. I can get the client to authenticate no prob, Inside machines can ping and communicate with the client with no prob. Client cannot ping, map or do anything inside without me adding a permit statement for 192.168.11.x to 192.168.10.x which is applied to the outside interface. Why do I need this statement ? Is there any way around this ? I think it is very un-secure to have to permit something like that on the outside interface, poses a huge security problem if you ask me. Below is a sanitized config.
Thanks,
Brian
