SOCKS proxy

aksher · ‎07-23-2008

Can any one make clear on SOCKS proxy. My understanding is that the traffic from SOCKS can pass thru the Firewalls and internet gateways unless UDP port 1080 is blocked.Correct me if am wrong.

Also want to explore alternative option for allowing VPN client traffic through http server proxy instead of opening "ipsec over TCP port 10000" on intermediate Firewalls

SOCKS allows to work with any (version SOCKS 4 - with TCP, SOCKS 5 - with TCP and UDP) protocols. A socks proxy simply transfers data from a client to a server, not penetrating into this data contents (therefore it can work with HTTP, FTP, SMTP, POP3, NNTP, etc.).As SOCKS proxies transfer data between computers without changes, it easily allows to create chains of SOCKS proxy servers of arbitrary length. However, for creation of these chains it is necessary to use special programs, as usual software is capable to use only one SOCKS proxy.
