Hi all.
I just installed SuSE 9.0 and trying to configure it the way I had 8.2
configured.
I basically retrieve and send email by tunneling through ssh like so:
ssh -l myusername -L5110:my.remore.server:110 -L5025:my.remote.server:25
my.remote.server
This as you can guess opens local ports 5110 which it tunnels to port
110 on the remote machine and local 5025 which it tunnels to 25 on the
machine.
If I turn on the default firewall config via Yast2 the connections take
very long to get establised. (3-4 minutes before I see the POP3 server
prompt)
If I turn it off then the connections are instant.
This didn't use to happen on 8.2
Does anyone know what the problem might be?
For the firewall config I specify ppp0 as the external interface since
I'm on ADSL and I say that I don't want protection from the internal
network.
any help much appreciated...
