I just brough 2 Linksys RV042 router for VPN connection. A site IP: 10.2.64.0/22 B Site IP: 10.1.68.0/22 (RV042 router 10.1.68.10) For the Lan port of the RV042 only support 24 bit. So I use a router between Lan and the RV042 and the connection to RV042 is 192.168.63.0/24 (internal router 192.168.63.10 and RV042: 192.168.63.20) I have setup a VPN connection for both RV042 and it connected. But I use the ping tools in System Management, it is fail to ping each other. (ie, I ping 192.168.63.20 or ping 10.1.68.10) I check the route table is correct but still can't ping. Any one can help me?
