Debian VPS <->Iphone client - HTTP proxy VPN traffic problem

willy87

Hi guys!!
I have server1.conf and server2.conf that are running correctly also tre traffic is routed corretly;
Server2 is linked with client2 (just same configuration of client 1 but under http proxy).
I follow this instruction:

Configure OpenVPN on server side by adding port 443 and proto tcp-server to the configuration file.
Configure OpenVPN on the client side by adding port 443, proto tcp-client and http-proxy 172.27.X.X 8080 to the configuration file.

But I cannot surf: it is connected on VPN correctly but no surfing.. no traffic after connection estabilish.. :x

Should I set a particular rule to iptable?
Like:
"iptables -t nat -A POSTROUTING -s 10.8.0.0/24 -j SNAT --to-source 172.27.X.X?
(172.27.X.X proxy http server)
It could work?

Can the VPS server has both rules?
"iptables -t nat -A POSTROUTING -s 10.8.0.0/24 -j SNAT --to-source 172.27.X.X (proxy http)" and "iptables -t nat -A POSTROUTING -s 10.8.0.0/24 -j SNAT --to-source 185.115.243.227 (vps) ???

Any suggestions?

Thanks guys for helping me 🙂

Obvously in the proxy win pc i have a script that starts every 15 minutes (15 minutes otherwise it drop down) just to avoid to install free proxy software:

netsh interface portproxy add v4tov4 listenport=4040 connectaddress=proxy connectport=8080
netsh interface portproxy delete v4tov4 listenport=4040
netsh interface portproxy add v4tov4 listenport=4040 connectaddress=proxy connectport=8080

If you can give me suggestions also regarding this script I will be really happy!
But the main goal of this thread is how can I surf behind my http proxy! :geek:

Thanks again guyssss

willy87

Hi Traffic!
Thanks for your reply!
I didn't understand well..
So I am a newbbb :geek:

1) What can I modify and adjust in Iptables?

2)And I should insert this in server2.conf instead of old one?

server 10.11.00 255.255.255.0

I explain better:
I need to use VPN with 2 different wifi network:

Server1 and client1 = normal 3G data o free wifi networks

Server2 and client2 = work network under http proxy

With privatetunnel.ovpn i simply switch between networks through openVPN settings - proxy button enable/disable

If I do the same with server1.conf and client1.ovpn i receive HTTP proxy
error..

3) It could be hard to built same configuration of privatetunnel with my home made VPN?

Really Thanks for help me!

EDIT:
What about this iptables rules for my VPS? Check specially last 3 parts please..
It would be marvellous if we do it!

I do not know how your network is configured so this is just for example .. you must configure this yourself:

Server 1:

I don't know because it is on VPS debian...
on the same VPS running server1.conf (for no proxy connection) and server2.conf (for proxy http connection).

I know that using client1 (for server1) is working fine and surf the web (through VPS). Using client2 (when I am behind server http proxy) no internet browsing..

Thanks for helping me.. I'm niubbb. 😛
