Got a question on multihoming and the use of stateful firewalls: Suppose customer "X" has two internet gateways, one in NY and one in LA. Traffic goes out the NY gateway, but for some reason, asymmetrical routing sends the return traffic to LA. Assuming the customer is using stateful firewalls, will the return traffic in LA be blocked? Is there any mechanism for the LA & NY firewalls to exchange stateful information? So far, the only solution I see to this issue is to tinker with route advertisements to prevent or minimize asymmetrical routing. Thanks in advance. irwin ----- Irwin Lazar Senior Consultant, The Burton Group e-mail: ilazar () tbg com Office: 703-742-9659 Cell: 703-402-4119 http://www.tbg.com/ _______________________________________________ firewall-wizards mailing list firewall-wizards () nfr com http://list.nfr.com/mailman/listinfo/firewall-wizards
