My topologic is :
Host1(MyL2TP Client) <=========> Host2 (L2TP Server, SOCKS5 Proxy Client) <==========> Host3(SOCKS5 Proxy Server) <======> Internet
Host2 is ubuntu14.04, how to redirect streams from L2TP server to Socks5 proxy? (or Http proxy?)
Thank you @drookie for your reply. My situation is L2TP protocol is blocked by the Firewall, so I have to get to the Internet via private protocol(between Host2 and Host3), But user does not have a client that support this protocol, So I use L2TP/IPSec
Is this impossible?
