Setting up Multi Wan pfSense with dansguardian + squid on other box

[kaze]

Hello I have trouble with this setup,
Running pfSense 2.1 with 2 wan, I have a dansguardian + squid instance running ok on another box in the lan,
if I setup the dansguardian on the proxy configuration of the clients machines everything is ok,
if I try to make an "Firewall: NAT: Port Forward" rule to map any port 80 destination to the DG box it does not connect at all.
Any tips ?

Can you check with tcpdump if packages are reaching dansguardian?
Did you excluded dansguardian ip from this forward rule?

Nope I didn't find out how to exclude the DG ip from nat rule.

Create one before this one, add dansguardian ip and enable option "No RDR".

Without it, the rule creates a loop between proxy server and firewall.

Thank you very much I'll will try this tomorrow as I don't have access to the server right now,
I was sure it wasn't looping since the remote DG access.log wasn't showing any activity.

Unfortunately not working, the DG host see my machine connecting :
tcpdump:```
08:49:34.944203 IP munnin.blkz.net.8080 > 192.168.0.99.51708: Flags [S.], seq 2341763301, ack 4041716888, win 65535, options [mss 1460,nop,wscale 6,sackOK,TS val 1498471935 ecr 35021758], length 0

But never connect back.

Here are my pfsense rules and nat:
