Hi, The network topo looks like this: the original network: router1 router2 | | |----------------OSPF------------| the target network: (we need to insert a transparent firewall between these 2 routers, so a proxy arp is set up on firewall to bridge router1 and router2) router1 firewall router2 | | | | |------OSPF-----| |---OSPF-----| 10.0.0.1 10.0.0.2 10.0.0.4 my question is: is an osfpd required on firewall to allow ospf traffic to pass through? or proxy arp has done this job already? thanks very much! _______________________________________________ LARTC mailing list LARTC@xxxxxxxxxxxxxxx http://mailman.ds9a.nl/cgi-bin/mailman/listinfo/lartc
