NAT on ASA not working, leading to Clientless VPN failing
Cisco Adaptive Security Appliance Software Version 8.3(1)
Device Manager Version 6.3(1)
I have a Cisco ASA5520 that I have setup to allow a GRE tunnel through from a router at site B. This all works fine when I use the below NAT with associated router object on the inside
object network SWTEST
nat (inside,outside) static interface
My problem comes in that this kills off my Cleintless VPN connection to the same firewall, I changed my NAT to point at another of my statically assigned IP addresses, and then nothing works. Can anyone help with what I've done wrong, or what i should do? My rule base allows any GRE in from the source, and rules all look fine
I'm guessing that I should do the below, but it doesn't work
