TCP port forwarding by name...

[thornc]

I wanted to replicate something like this....

I'm behind a firewall and can't access IMAP/POP/SMTP. Can you help?

AAA has a special proxy system whereby you can access each service (POP, IMAP or SMTP) through any port number. The server names are:

IMAP: imap.proxy.aaa.bbb
IMAP/SSL: imaps.proxy.aaa.bbb
POP: pop.proxy.aaa.bbb
POP/SSL: pops.proxy.aaa.bbb
SMTP: smtp.proxy.aaa.bbb
SMTP/SSL: smtps.proxy.aaa.bbb

If you use these server names, you can use any port (except 80) to access these services. Commonly open ports are 21, 25 and 443. Note that if you use SSL you'll get a warning about a non-matching certificate (it's set to 'AAA"'): you can safely ignore this.

Is there any program around that can do it, whitout having to have an ip address to each sub.domain?
Sort of a catch all tcp incoming and automatically forward it to a predefined hostort!!

Thanks for any comments in advance....

You would need something that understands the protocols and can forward based on those. Don't know of anything off hand that can do this though.

I don't understand what is the problem, but if you need to detect protocols using non standart ports there is
