Cisco ASA Tunnel Between Two ASA within the same /24

maileh

Level 1

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.
