Hi all ...
I'm using Mikrotik for gateway and Videocache + squid + frox in DMZ
It's work !!! file cached is unlimited traffic going to LAN
u can read my explainantion (sorry using indonesian languange hehehe you can translate it using google) in http://blog.glosit.net
simple explainantion :
1. first, squid will connecting to internet using default ip example: 192.168.34.2. Do not using this .. try to tcp_outgoing_address to other squid ip alias.
2. in mikrotik change tos/dscp come from ip address 192.168.34.2 (squid in dmz)
3. packet marking for that's tos/dscp for using in simple queue
4. make simple queue with unlimited traffic
This work !!!
May this help us
