[IMail Forum] The use of a firewall

[Stephen Pokora]

Hello   We are trying out Imail Express and I have question regarding the use of a firewall.  Our main network is currently behind a firewall and it is intended that the Imail server will be placed ‘outside’ with its static IP address. Should I rely on port blocking using TCP/IP filtering or should I install a McAfee or Norton personal firewall? We are only a very small office and we can’t afford any more equipment.  Is there a clever way of using our current hardware firewall without compromising the internal network?   Any suggestions or tips would be appreciated.   Thanks   Steve
