m0n0wall Forum - Local net != LAN Subnet

I have a m0n0wall with 2 ipsec VPN.

My LAN is 192.168.180.0/24

1) the first VPN (A) define the "Local subnet" to LAN Subnet

2) the second VPN (B) define the "Local subnet" to Type "Network" and "Address" = 172.16.186.16/28

(A) pinging a remote machine from my local network works well..

(B) when m0n0wall receive a packet from the LAN interface with a source address in 172.16.186.16/28 range and a destination address in VPN (B) remote net , the firewall drop the packet.. despite i have added a firewall rule.

Any idea ??
