I'm pulling my hair out here. I've been working on this for days without any success. I've whittled the ruleset down to the barest possible rules and even that doesn't work. I'm at my wits end. I would really appreciate it if someone could show me where i'm being a complete and total moron. Here's the situation. I have a somewhat unique environment. It consists of 2 WAN's, an internal LAN, and numerous VLANS (isolated clients, which need to be accessible from the internet, but not to each other). This runs in a VMWare esx server, but that's not really important. FreeBSD 7.0-RELEASE em0 = lan (10.0.0.x) em2 = WAN1 (y.y.y.y) (dhcp) em3 = WAN2 (x.x.x.x) (static /28 subnet) the default gateway is on nic2. nic3 will need to forward ip:port's to various vlans. nic2 is used for all outbound lan traffic (internet). nic2 will need to failover to nic3 eventually, and nic3 will have to failover to nic2 (for outbound, obviously no choice for inbound). So here's the problem. I can't even get nic2 or nic3 to respond to a ping request from outside my network when pf is enabled. I know the interfaces are set up correct, as I can ping the default gateways of both interfaces. Also, outbound NAT works perfectly on wan1. Here's my ruleset. lan_if="em0" wan1_if="em2" wan2_if="em3" set block-policy return set skip on lo0 nat on $wan1_if from $lan_if:network to any -> ($wan1_if) block in log pass out log keep state pass in log inet proto icmp all icmp-type echoreq keep state pass in log quick on $lan_if Looks simple enough, right? Why won't it work? All i want is to get a ping from both of the firewalls WAN's from outside the network. Any ideas?
