I am running a Debian etch server, has been working relatively ok, on one IP address. Have the option of a second IP address. Only problem is, everytime I enable the second address, the server goes down after a short while. I suspect firewall or intrusion to be the problem. How do i secure the second ip like the first one. Want to set up something like: eth0 (net) external connection eth1 (loc) internal. Have tried looking at ssh setup, but there is no hostname or ip to set or configure for each address? There is no entries in hosts.allow or hosts.deny would this cause a problem? Would greatly appreciate any help or guidance.
