Hi
I have this Scenario.
LAN1 --- ASA1:192.168.1.158/27--------CORE---------192.168.1.48/26:ASA2-------LAN2
If you note both the ASA's Internet IPs are on the same /24 but with in respective smaller subnets where i used this private ips just as an examples.
When i captures i don't see anything initiates from these two ASA regarding the tunnel inital phase. However if i ping from LAN1 and LAN2 it is work as expected.
I assume that the local ASA aware of the remote ASA reside in the same /24 therefore it wont form the tuinnel in the first place.
I hope this makes sense. Please if this is correct please someone would let me know the documents for it so i can see other options.
FYI
These two ASA both have Tunnels to other VPN's Gateway on a totally different network and of course those are perfectly working except the tunnel between themselves.
Thanks.
