Proxy server routing

[Masterdam54]

Dear all,

At the moment we have an ISA proxyserver that i want to get rid of. Now we have pfsense with proxyserver.

I cannot make the upstream proxy work and i guess thats because of the routing doesnt work. I dont know where i go wrong and can use some help.

Isa server has a chaining proxy to server 192.168.0.6 port 3128 SSL 8443
Route print give 192.168.0.6 255.255.255.255 172.16.0.204

Now i added this route in Shell to the pfsense
route add -net 192.168.0.6/32 172.16.0.204

route to: 192.168.0.6
destination: 192.168.0.6
      mask: 255.255.255.255
    gateway: 172.16.0.204
        fib: 0
  interface: igb1
      flags: <up,gateway,done,static>recvpipe  sendpipe  ssthresh  rtt,msec    mtu        weight    expire
      0        0        0        0      1500        1        0

After this i still cannot ping 192.168.0.6

When i add this route on my windows machine, i can ping 192.168.0.6.

On PFsense it is not working.

I have a few question, on which interface i should add this route to LAN right? I tried both, both didn't work.

All information is welcome.
