Multihop SSH with Putty and Socks5 Proxy

Requirement:

I wanted to access a server (Centos 7 on port 22421) at home behind a pfsense firewall and I was at work.

The pfsense firewall allowed traffic from an intermediate host but not from my machine at work.

The pfsense firewall was setup to allow traffic from my intermediate host with public key authentication

From work I could ssh to the intermediate host.

To access the pfsense GUI I had to use a browser and do a SOCKS5 proxy to the intermediate host and I wanted to setup a multihop ssh with putty to intermediate host and then to my home server.

I was able to setup SOCKS5 proxy and multihop ssh in putty in a single putty connection configuration.

I use a dynamic DNS to map a hostname to my dynamic IP provided by my ISP.

I have already done the step of port forwarding any SSH request that come on the ISP provided modem/router to my Centos 7 server.

1. Start putty and on the “Session” page of the “Putty Configuration Dialog” that appears, fill in the host name and user name  for the final destination host (my Centos 7 server and port 22421). 
2. Switch to the Connection –> Proxy page, select “Local” as the proxy type enter the following as the local proxy command: plink.exe intermediate.proxy.host -l username -agent -nc %host:%port
3. go to Connection -> data and set the auto-login username 
4. go to Connection -> SSH -> tunnels and setup dynamic port forwarding   Select Destination as Dynamic, source port as any number greater than 1024 , In my case i set it to 7002 in Source port field.         Click on ADD
5. Save the session.

Now in Firefox setup Socks5 proxy

In Firefox Settings -> Options -> advanced -> Network settings -> Manual Proxy configurations 

Select SOCKS host as localhost , enter port as 7002 , choose Socks v5 radio button 

Click OK,

Now use putty to open the connection setup earlier and then in Firefox url type the url for Pfsense (In my case it was 10.0.0.1 ) and Viola my pfsense login screen comes up,
