Hello fellow pfSense'ers! I've been using NAT to redirect TCP/80 traffic on a 
subnet to a squid proxy server for quite some time. However, I've found that if 
I use this functionality on any additional interfaces, connectivity to the 
squid box gets extremely flaky. Running a constant ping shows that traffic to 
the squid box is randomly getting dropped. Keep in mind that the squid box is 
on a different interface/subnet that does NOT have web traffic redirected so I 
know that squid is not being redirected to itself... I found that one out the 
"long" way...

Before run a tcpdump or throw a hub between the squid box and the pfsense box, 
I'd like to know if this is a known problem or if anyone has heard of it? My 
NAT rule is as follows:

Int      Proto   Ext Port        NAT IP     Int Port Range     Description
LAN      TCP     80 (HTTP)       10.0.0.10   8080              send http 
traffic through squid box

Hopefully everyone is using a monospaced font in their email so my NAT rule 
above doesn't get all hosed. 

All comments and ideas are welcome and appreciated. Thank you!
