Firewall/NAT

[Here is the config of Zywall 35:]

Hi All,

I've un little problem,

I installed un router ZyWall 35 in my network for tests.

Here is the config of Zywall 35:

WAN: (It's a private address because it's for tests)

IP: 172.22.52.163
Subnet: 255.255.255.0
GW: 172.22.52.1

LAN Network: 10.0.0.0 / 24


M0n0wall has IP address 172.22.52.1

When un user is connect to the LAN port on the ZyWall, he can access to the Internet, BUT impossible to access a HTTP server (172.22.52.137) on Network 172.22.52.0/24.

In m0n0wall logs I've this:

X 11:44:25.123106 LAN 172.22.52.163, port 10910 172.22.52.137, port 80 TCP

Why the packet is blocked? :-(

Thanks !! :-) ;-)

No solution? :-( 

Zyxel Support tell me that the problem comes from m0n0wall installation.

They say that I have to activate the function "asymmetrical route" in m0n0wall
but I don't found this function.... It's possible to do that?

Thanks !!! :-)

That's the "bypass firewall rules for traffic on same interface" on Advanced page.
