I am setting up a Pix 506e for a client who has a Exchange2000 server. Currently the client's only option is to use Cable broadband service, so the external interface is on dhcp. We are limited to one ip address which is dynamic. Can we set-up port redirection on the external interface of the pix to allow smtp traffic to the internal exchange server?
Assuming we change the MX record to point to the external ip. Will this work:
static (inside,outside) tcp interface 25 192.168.1.x 25 255.255.255.255
access-list 110 permit tcp any host interface eq 25
access-group 100 in interface outside
1) Will this work?
2) is the syntax correct?
2) Should we diasable mailguard? (we are using exchange 2k)
