Re: problems routing to DMZ from outside

From which network are you trying to access the DMZ ??

From the inside or outside....

From outside, you need a conduit or access-list configured to allow connection from outside to dmz.

Re: problems routing to DMZ from outside

from outside i have the following accessl ist on the out side interface of PIX

access-list outside_access_in permit tcp any host x.x.x.130 eq smtp

access-list outside_access_in permit tcp any host x.x.x131 eq smtp

access-list outside_access_in permit udp any host x.x.x.130 eq domain

access-list outside_access_in permit udp any host x.x.x.131 eq domain

access-list outside_access_in permit icmp any any

access-list outside_access_in deny ip any any

Re: problems routing to DMZ from outside

Have you applied this access-list on the outside interface as follows?

access-group outside_access_in in interface outside

Also check if there is a static translation for the ip addresses x.x.x.130, x.x.x.131 into the local ip addresses of the servers in the DMZ. (Use static command)
