Just to repeat the gist of my question (slightly re-worded): ------------------------------- I have the lines #INTERFACE SOURCE ADDRESS PROTO PORT(S) IPSEC MARK eth0 eth1 in /etc/shorewall/masq on my server. ------------------------------- My question is: what exactly is the effect of this? Does IP masquerading by default only apply to the firewall server to modem interface (eth0 in my case)? And does the above line mean that it will also be applied to packets reaching the firewall server on the eth1 LAN? I couldn't find a clear account of the effect of the line anywhere in the shorewall documentation. -- Timothy Murphy e-mail: gayleard /at/ eircom.net tel: +353-86-2336090, +353-1-2842366 s-mail: School of Mathematics, Trinity College Dublin -- users mailing list users@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe or change subscription options: https://admin.fedoraproject.org/mailman/listinfo/users Guidelines: http://fedoraproject.org/wiki/Mailing_list_guidelines Have a question?
