Which service?

Sophos Anti-Virus Web UI
You could proxy the requests - if it is http traffic than with web proxy (squid, apache mod_proxy).

Otherwise a TCP or UDP proxy (http://en.wikipedia.org/wiki/Netcat, http://www.boutell.com/rinetd/, http://www.xinetd.org/)

Iptables (kernel) has some limitations to redirecting to

As it is not possible to change the port the Web GUI is listening on, you can do one of the following:
- use command line tools to perform every task that is configurable from the Web GUI. For more details refer to the Sophos Anti-Virus for Linux User Manual.
- use 3rd party tools like rinetd to redirect port 8081 to another additional port to listen on.
I suggest you  install VNC  anduse VNC to connect  to it. I read the manual here and I dot think its possible.. http://www.sophos.com/sophos/docs/eng/instguid/linu_sen.pdf
You could also use rinetd to forward the appropriate port from a normal to the loopback ip.

rinetd.conf 80 80
