Intra interface

richard.gosling
Level 1
Level 1

Hi

Bet no one can solve this one

I have a cisco ASA and 2 877

The outside interface is connected to the internet, nothing on the inside

The 2 877 are also connected to the internet.

I have 2 VPN's that connect to the outside of the ASA.

Both tunnels are up.

But am unable to ping from one 877 to the other 877 via the VPN's.

I have intra interface enabled and sysopt connection permit-vpn

Tho I did set the vpn's up with match address statments.

I have been on this for ove a week and im starting to lose the plot.

Any help very much appricated.

Richard

Thanks m8

Not really a CCIE question was it.

Been messing around with everything but so obvious.
