David and Bob,
Thanks for your replies.

I'm afraid that I don't know the status for outgoing. Only that the
router should block all incoming even though the in/outgoing FW
options are disabled.

Can you explain what the meaing of incoming is? Does it mean all
traffic to my system or does it mean just attempts to establish a
connection to my system?

In the configuration I have a FW option where I can enable in- and/or
out-going FWs. For each direction I can choose allow/deny all
in/outbound traffic except a number of configurable IPs and/or port
numbers.

The manual says the incoming FW will only apply for DMZ and local
"virtual servers (ftp/http...)"

I tried setting the outgoing firewall to deny all except
20,21,25,110,119 and 443. This blocked all communication for web and
mail. Now I deny only 137-139. I am going to check with my ISP for any
required ports, guess I should have done that long ago.

Yes the FW has a logging function that gives me info like:
Friday, November 22, 2002 21:10:01 Unrecognized access from
4.62.124.65:1029\
        to UDP port 137
Friday, November 22, 2002 21:37:12 Unrecognized access from
62.255.196.93:1026\ to UDP port 137

I am a bit confused here and hope you can spare me a few more minutes
on this

TIA,
Tom
