Hi,

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.

Much appreciated.
