Traceroute does not use the proxy

(1/1)

neo:
when i give a trace in the traceroute it gives as unknown host.
i have correctly installed the proxies and am behind a firewall.

dalek:
From what I have read some specific ports must be open for traceroute and ping to work.  I'm not much on it because I'm on dial-up.  I can google though.  I found these.

The first one will tell which ports need to be open.  They both may be good to read.

Hope this helps.

Ya.. he is right..
When using proxy .. some commands like ping and traceroute etc. will not work untill they are allowed by the proxy.
I m sure u r not able to use ping too.

neo:
man i am having a http proxy and connecting to port 80
now what exactly should i do to :
1) traceroute
2) scan hosts with nmap
my network admin is not listening.
the links given by dalek talks about ip forwarding and masquerading how to do that.

Thank you!.
