Hi- hope someone can help with this one.
I've a PIX501, with a fairly basic config: patting an RFC1918 network on a single public IP (PIX's outside interface), PIX is a PPTP server with local authentication, and, up until now, any traffic has originated on the inside and is headed outbound.
Anyway: I now want to forward https (443 on tcp) into my network, to allow Microsoft webmail into one of my servers, on 192.168.2. Fairly straightforward, you would think...
So, I add the following 3 lines:
-access-list webmail_in permit tcp any host (PIX-EXTERNAL-IP-ADDRESS) eq https
-access-group webmail_in in interface outside
-static (inside,outside) interface 192.168.1.2 netmask 255.255.255.255 0 0
However- after I add the static in, oddly, this then knocks out internet access to my other LAN clients- apart from the server on 192.168.1.2!
I'm really stuck on this one.
Anyway, if anyone cares to delve in, here's my sanitised config:

Your config is a little off. You have only 1 external ip address so if you static that address to 1 internal host all other host won't have and addres to translate. The static needs to have the tcp port translation. Try the following
static (inside,outside) tcp interface 443 192.168.1.2 443 netmask 255.255.255.255 0 0
access-list webmail_in permit tcp any interface outside eq 443
access-group webmail_in in interface outside
Thanks,

Chad, thanks a lot. I had assumed that the acl would cover what the static would translate, port-wise. I will try this out.
Cheers-
