I'm trying to create a WCCP connection between my Squid server (on 10.9.10.10 - inside LAN) and my ASA 5510 (inside: 10.9.254.1 - outside 201.234.x.x). WCCP/GRE tunnel works perfect, they see each other, i've seen I_See_You and Here_I_Am packets. The problem is that when ASA gets the packet, it redirects alright to the Squid but with the wrong ID, because it's using its outside IP which cannot be reached from inside.
I found out that Router ID is created using higher IP configured. I tried unassigning ip addresses in every interface except inside, creating WCCP web-cache, and it does work, but the moment i assign the rest of the interfaces IPs it takes outside IP as ID again.
Is there any way that this Router ID can be changed manually?
