client calls financial-gw.tesla.cn through 3proxy socks.
most requests are sucessful.
but sometimes error.
tcpdump shows that after recieved client socks connect request(tcpdump No.8), 3proxy didn't try syn to financial-gw.tesla.cn as usual, but reply socks connect Succeeded in 2s with port 1080 (tcpdump No.10).
and then send fin to client immediately.
client sends request after success socks connect, which reseted by 3proxy.
the error occured.
maybe socks source port 1080 conflict with socks service port 1080?
please see attachment tcpdump (x.x.166.86 is client, x.x.46.98 is 3proxy).
thank you.
