Hi Henrik, Now I upgrade and compile squid to 2.6Stable5. If squid.conf configured not to use specific ip address on tcp_outgoing_address, there an error messages on cache.log as shown below. How ever with this config I'm able to browser website but unable to spoof client ipaddress. 2006/11/04 02:25:03| tproxy ip=192.168.1.2,0x1b9f5bcb,port=0 ERROR ASSIGN 2006/11/04 02:25:08| tproxy ip=192.168.1.2,0x1b9f5bcb,port=0 ERROR ASSIGN 2006/11/04 02:25:12| tproxy ip=192.168.1.3,0x1c9f5bcb,port=0 ERROR ASSIGN 2006/11/04 02:25:15| tproxy ip=192.168.1.2,0x1c9f5bcb,port=0 ERROR ASSIGN and If I'm using specific ip address, the error messages as below and none can't access websites. 2006/11/04 01:05:46| commBind: Cannot bind socket FD 16 to 192.168.1.3:0: (99) Cannot assign requested address 2006/11/04 01:05:46| commBind: Cannot bind socket FD 16 to 192.168.1.2:0: (99) Cannot assign requested address 2006/11/04 01:05:46| commBind: Cannot bind socket FD 16 to 192.168.1.3:0: (99) Cannot assign requested address any help would be great.
