Pure NAT Issue with Transparent HTTP

[manjeet]

Hello Guys, Currently i am running Sensei plugin for web filtering which does not have cache feature. Most of my network system are Ubuntu and updating from command line uses HTTP so i use squid Transparent HTTP for that purpose. It works for me all fine.

I am running internally a web server which i access from outside as port forwarding from WAN and it works internally as well. With "Reflection for port forwards", "Reflection for 1:1" & "Automatic outbound NAT for Reflection" enabled, i can access it with WAN IP from internal / LAN network.

Only issue is that when i access web server (Port 80) from inside with WAN IP with Transparent proxy enabled, it will not pass that traffic and after a minutes of trying to access the link it just timed out. If i disable proxy then it start working all fine.

I need transparent http for cache and sensei for web filtering & logs so If anyone has any solution please provide..
