I am on a wide campus network and network administrator of my hostel. Hostel server is running RH 7.3. Now the problem is that there is a senior student in my hostel who has been provided access to a proxy server, say 192.168.1.1 ... which lays far away across a number of hops...
I tried to SNAT on hostel server using
iptables -t nat -A POSTROUTING -s <myIP> -d 192.168.1.1 -j SNAT --to-source <senior'sIP>
Now i was connected to the proxy but the senior was no longer connected. Is there anyway that we both can use his connection???
Don't tell me to run proxy on senior's pc... I don't want the senior to know that i am using his connection... Just tell me something that i related only and only to my hostel's server...

All you need to do is add a static route in your pc (or the hostel server) to the proxy so your networking can find it.
If there are multiple hops, you will need multiple entries to define each net between...

Okayyyy....
Now let me put this in a more explicit way...
Its not about routing. The squid on proxy server allows only a few IPs to connect to internet through it...
Now when i used
iptables -t nat -A POSTROUTING -s <myIP> -d 192.168.1.1 -j SNAT --to-source <senior'sIP>
i got through the proxy server, but the senior got reject from proxy..
The question is: how can i manage to get through the proxy in a way that my outgoing packets have the senior's IP as source IP... and still senior is not knocked off the server...
