I recently worked out a basic configuration to provide a 3 interface firewalling scheme. Inside, outside, and dmz, on the subnets. 10.200.251.0, 10.200.252.0, and 10.200.253.0 with mask 255.255.255.0. After realizing that I need to upgrade versions from:
Catalyst 12.2(17d)SXB11, FWSM 2.3(2)
to
Catalyst 12.2(18)SXF5, FWSM 3.0(1)
Now the traffic that was foing thru on a ping will not go thru, all I get is timeout errors, no deny's or anything else.
anyone else have issues when upgrading versions
