We have FWSM 3.1 configured on 6500 IOS ver 12.2(18)SX7
Various DMZs have been created and Natting has been done for DMZ to Outside traffic. Facing a problem in natting for WINS traffic.
Servers/clients register themselves in WINS server(placed in a DMZ) using their local IP. But clinets from outside would connect to servers using their translated IP.
But since the WINS registration has Local IPs instead of translated ones, WINS resolution is not happening from clients to servers.
We have tried disabling inspection engine for netbios, keeping WINS server at outside etc. etc. but of no use.
Earlier we were using FWSM ver 2.3 with same configuration, but WINS resolution was working perfectly fine.
