Hi,
I have a new ADSL connection for our office, and a new firewall behind it.
I pointed a proxy server (squid) to it, and.. it works most of the time.
Just a few websites don't seem to like it. E.g.:
1385361294.211 18410 192.168.50.199 TCP_MISS/502 1217 GET http://www.zeit.de/index - DIRECT/217.13.68.220 text/html
There are a few sites that don't work, most of the time it is a 502, occasionally a 504.
I suspected the new firewall but cannot see any related packets dropped (and logged) there.
Check that you haven't disabled the "forwarded for" setting in squid.
Thanks, I will keep that in mind. However, the same config works on the ADSL line in production. I stripped back the whole network just to have my own PC directly on it. MTU to 1492, 100MBit/s full duplex to the NetComm NB9WAXXTLAN modem, no proxy or so - still the problem exists. Weird that only some worksites don't work.. it's a bit how a friend living over in China describes it - randomly some stuff is blocked. I hope we are not there yet.. Well, at the end I lodged a fault at the ISP. Will see what comes out of it. Sadly I did not catch the problem last weekend when installing. It frustrated people Monday morning so I moved back to the old line. Thanks again Peter
