[Fwd: Re: Firewall - How blockade the files .exe]

[roni02@inf.its-sby.edu]

overview
- i have one visible ip and 4 server in internal networks.
- every server have one ssh server that listen on port 22.
- on visible ip i installed debian + regular firewal + dns + apache for
virtual proxy that forward to internal server.

question
1- how to make ssh service like virtual proxy in apache.  ?
  example: when someone use ssh server1.mydomain.com will forward to
internal server (192.168.0.5) in same port (22)
            then someone use ssh server2.mydomain.com will forward to
internal server (192.168.0.6) in same port (22) and etc.
   now i use port forwarding ( server1.mydomain.com:22 forward to
192.168.0.5:23,server1.mydomain.com:22 forward to 192.168.0.5:22)
2. there is any rules in iptables to filter by domain name not ip address ?


any suggestion/explanation/link etc will be appreciated
thanks for everythings and sorry for my english :)
