MRTG problem on WAN
-
Hi everybody. I'm trying to use MRTG and pfsense but I have problems.
My pfsence has three NICs:
a NIC for WAN
a NIC for DMZ
a NIC for VLANs
When my win-pc sits on DMZ, I'm able to monitor DMZ-traffic.
When my win-pc sits on VLAN, I'm able to monitor VLAN-traffic.
When my win-pc sits on WAN, I'm able to monitor WAN-traffic.But when I try to configure MRTG, from my win-pc sitting on DMZ, in order to monitor WAN-traffic I get the following error:
SNMP Error:

I am guessing this is the general case where you can't access a pfsense port on the WAN from inside the LAN (or DMZ in this case.)
-
So, it's just a rule problem or it is not supported by pfsense?
-
As danswartz mentioned, this is probably just a rule problem. Show us some screenshots from your DMZ firewall rules…

27-bit masks to both wan and dmz (different nets).
