Re: [suse-security] SuSEfirewall 2.1 and NetMeeting 3.01
Ok, I have added the ip_masq_h323.o module and re-started masquerading to load the module. SuSEfirewall is still in place as before. I can now use NetMeeting 3.01 on a PC to connect to a hosted meeting outside the firewall. My question now is how do I allow external NetMeeting clients connect to a NetMeeting host on our internal/private network. Any help much appreciated :) MR Torsten Mueller To: michael.ryan@storm.ie <torsten@arch cc: suse-security@suse.com esoft.de> Subject: Re: [suse-security] SuSEfirewall 2.1 and NetMeeting 3.01 06/29/2001 12:41 PM Hey, i use a setup with a netmeeting kernel module and portforwarding.

Anyone done this before? any advice on how this can be done securely?
tnx in advance,

Hey Michael, i use a isdn dialup line to connect to the internet. I changed the /etc/ip-up script and added the portforwarding for netmeeting (and icq). This is the netmeeting part: #netmeeting anrufe von draussen /usr/sbin/ipmasqadm portfw -f /usr/sbin/ipmasqadm portfw -a -P tcp -L $LOCALIP 1720 -R 192.168.100.5 1720 /usr/sbin/ipmasqadm portfw -a -P tcp -L $LOCALIP -R 192.168.100.5 1503 echo "setze portforwarding fuer netmeeting eingehende anrufe" The problem with this config is, that you can only use 1 host in the intranet to receive the netmeeting calls from outside the lan. Another solution would be to use a gatekeeper, but i havn't tested this. Hope this helps. Greetings Torsten michael.ryan@storm.ie schrieb:
