yes but the end that is seeing things as spoofed, is the NEW end. Also, I did rebuild the VPN from scratch.
any other ideas?

Question
Cannot ping over IPSEC VPN between ZyXel ZyWall 5 and pfsense
I am replacing one end of a site to site IPSEC VPN. Both ends used to be pfsense but now on one end I am using a ZyXel ZyWall 5. I believe I have the two endpoints negotiating both phases properly, and the VPN shows up as active and working in both the pfsense and ZyWall interfaces. I just cannot ping either network from the other side. the main office network (with the pfsense) subnet is 10.10.10.0 /24 and the satellite office network (ZyWall) is 192.168.10.0 /24.
as far as firewall rules go, on the pfsense I have an IPSEC rule that traffic is wide open (works on all other VPN endpoints) and on the ZyWall i have the default setup, which is OPEN.
Here is a line from the ZyWall logs which I think describes a computer at the main office trying to ping the ZyWall:
# Time Message Source Destination Note
3 [xx] ip spoofing - WAN ICMP (V to V/ZW, Echo) 10.10.10.25 192.168.10.1 ATTACK
thanks!
