Hi everyone!
I’m having some problems getting a VPN connection running to a PIX 501.
I had it running – started to fiddle around – and now for some reason I can’t get it back to work 🙁
Some info in advance:
– not an expert in in-depth networking or encryption at all
– used the vpn-wizard (not really firm with cli)
– connecting via Cisco VPN client
– RADIUS authentication via MS IAS (has worked but don’t get that far now…)
– I have already played around in this config looking at the prior working one so perhaps there are some really stupid things in here 😉
Really hope someone can help on this (also hoping it’s clear for the pro’s)
