RV220W IPsec tunnel connected, but no ping is working

Question

Hello,
I have a problem with my RV220w router and IPsec connections.
The tunnel is connected, but no ping is working. I have not changed any Settings on the Client Site or Router Site. The last succsessful tunnel wit this configuration is a half year ago.
The local and remote network have different ip-address.
I have both firmware versions 1.0.4.17 and 1.0.5.8 tested.
A tunnel over PPTP is working fine. The ping works successful.
Has anyone an idea?
kind regards
Martin Schubert

Answer 1

At the glance,
First, what are your netmasks for those networks? I suppose they are 255.255.255.0.
Second, check your Remote Security Group and Local Security Group on B and C for their tunnel. Maybe permutation?
Third, check Routing table (Setup->More->Advanced Routing then at the bottom Show Routing Table).
Should be something like - on B:
10.0.0.0
255.255.255.0
GW for B
10
ipsec0
and on C:
10.0.1.0
255.255.255.0
GW  for C
10
ipsec0
