Routing strange problem

blepas

Hello, i have a strange problem…

site A:

1 VLAN WAN internet ---
1 VLAN WAN Site B ---10.12.13.1
1 LAN--- 192.168.0.1

site B:
1 VLAN WAN internet ---
1 VLAN WAN Site B ---10.12.13.2
1 LAN --- 192.168.10.1

10.12.13.x/30 are a wireless point to point, transparent bridge.

The problem is:

I can ping from LAN site A to 10.12.13.2 and viceversa, no problem.
I can't ping from pc1 in lan site A to pc2 in lan site B, but when I try to ping from pc2 in siteB to pc1 in site A, both pings begin to respond....

so the problem is that ping (and all services) begins working when destination try to access source , no mather who begins and site who begins... when I stop traffic, in a few minutes, same problem...

very strange???

thanks.

SITE A:
WAN_VLAN5: ip: 10.12.13.1/30

Static routes:
192.168.10.0/24 wan_tositeB - 10.12.13.2 WAN_to site b

First firewall Rule in LAN:
IPv4 * * * 192.168.10.0/24 * wan_siteb none to site b
–------------------------------------------------------------------------------

SITE B:
WAN_VLAN5: ip: 10.12.13.2/30

Static routes :
192.168.10.0/24 wan_tositeB - 10.12.13.1 WAN_to site b

First firewall Rule in LAN:
IPv4 * * * 192.168.0.0/24 * wan_sitea none to site a

Is it enough for you?

Thanks.
