Hi good people,
I recently switched to Suse 8.0 on my server but I'm having a little problem...acutally its a whopper of a problem...if I run SuSEfirewall2 it will masguerade etc and
allow connections to the internet....but I can't get it to allow my clients on the internal network to access popfix on the server (i.e smtp)...it looks like I can pop the
server (port 110), although I'll admit I'm not sure since there are no mails to collect (but I'm not getting any errors).
On the server itself I can connect to postfix via telnet localhost 25 and everything seems to work but if I try to do a telnet to the server from a client it doesnt work
(whic is good because I dont want telnet). On my previous server (Red Hat 7.2) I ran a firewall script for iptables that worked fine....sooo..I figured skip SuSEfirewall2
and run the old script..but that doesnt work either and whats more if I do a port scan I find that I have ports availabe or at least not in stealth mode that where always
in stealth mode before, this despite running the very same script that I had before.
There is something about suse 8.0 and iptables that I'm not getting.
I have master.internet.server with two nics, eth0 is connected to the internet and eth1 is connected to a local lan (192.168.1 net). On the master.internet.server I run
postfix, other than that the clients should be able to surf on the internet, i.e do www connections. Which is what my old script basically did.
I'm hoping someone can point me the right or perhaps has a functioning script that as defaukt disallows everything and masqs the internal network, allows www and
My mailserver is down right now so any quick answers would appreciated and I'll make sure Santa Clause hears about it :)
