MRTG (SNMP) through a PIX


I have big problems trying to get SNMP info through a PIX firewall.

At our LAN segment, I have setup a Linux/MRTG PC, which I want to read info from our Internet router, placed at the external interface of our PIX: When I try to connect to the router from the MRTG PC, I got nothing. I have no problems getting info from switches etc., as long as they are placed at the same network as the MRTG PC.

What am I doing wrong ?

access-list outbound permit tcp host any snmp-server host inside poll

where is your inside MRTG PC

I would suspect that you have permitted the inside IP address to poll, but the PIX is translating it to a public IP address. If possible, map your graphing server to an open IP address and allow this in your list.
