Hello all, here is what I have going on

INET-----1-----3-----4
	    \
	     \
	      -----2
	   
Boxes
	1 (216.138.226.17)	= Main Firewall/Gateway (FBSD5.1)
	2 (192.168.1.5)		= LAN PC (WinSrv2K3)
	3 (216.138.226.25)	= Development Firewall/Gateway (FBSD5.1)
	4 (192.168.2.199)		= LAN PC (WinXP)

1 and 3 both have real IPs
1 and 3 are connected via a switch
1 and 2, and 3 and 4 are connected via separate hubs
2 and 3 uses 1 as gateway
4 uses 3 as gateway configured via dhcp from 3
1 and 3 uses IPFilter and NAT, 3 has no IPF rules loaded

Here is the problem, it is with the connection between 3 and 4, I can
ping from 4 to 3 but not from 3 to 4.
>From 4 I can ping 3, 1 and the Internet just fine.
>From 3 I can ping 1, 2 and the Internet but not 4. I find it interesting
that I can ping 2 (assuming via 1).
>From 1 I can ping 2 and 3.
Expectedly 4 can not ping 2, and vise versa, this is desired as
ultimately I will VPN 3 to 1 to have full routing between networks.

Here are the netstat -r results from 3
