I would like to know if anyone has any tips on troubleshooting L2L (and RA) VPN's. I usually use the ASDM wizard to create the VPN's and when it doesn't work, it get's messy.
I usually run the following debug:
no debug crypto isakmp 127
no debug crypto ipsec 127
Is there any way to determine why a tunnel is not coming up? anything with the ASDM?
The L2L config is fairly standard, nevertheless sometimes it doesn't work.
Any tips on troubleshooting and bringing a tunnel up.
