I'm trying to build an IPSEC tunnel between 2 PIX boxes. Both are running 6.3(5).
Pings from the device on PixA's inside network to the device on PixB's inside network say "Reply from #.#.#.#: TTL expired in transit."
Pings from the device on PixB's inside network to the device on PixA's inside network say "Request timed out"
In both cases the tunnel seems to be formed. When I issue the command show "show crypto isakmp sa" I see the tunnel is formed and is in the state QM-IDLE on both PIXes.
I've never used PPPoE on a PIX before. PIXB's outside interface is configured for PPPoE. I don't beleive this Pix is the problem though. I have successfully configured a VPN tunnel between PixB and AsaC.
The addresses in the attached file have been changed to keep privacy. Hopefully I changed them consistantly.
Thanks for your help!
