1841 Firewall with DMZ

I have a 1841 currently configured for firewall and NAT. I have a HWIC-4ESW module installed. What I would like to do is configure one of the ports on the module as a DMZ for a mail server. How would I best go about this? Thanks.

Re: 1841 Firewall with DMZ

Add securtiy bundle to 1841 which can be done by adding PIX.CBAC allows external traffic to access the services in the Demilitarized Zone (DMZ), but prevents specified protocol traffic from entering your internal network unless the traffic is part of a session initiated from within the internal network.Refer the URL for more informationhttp://www.cisco.com/en/US/partner/products/sw/iosswrel/ps1835/products_configuration_guide_chapter09186a00800ca7c5.html#wp1002187
