I have a little problem with two SonicWALLs connected between each other with a dedicated link in layer 2 from our ISP.
Let's call them SonicWALLs A and B. From SonicWALL A, the connection is done with a VLAN in the port X4:110, with the IP address 10.20.0.254 (encap dot1q). From SonicWALL B, the connection is from a physical port without dot1q. Is this the reason SonicWALL B is not able to ping the IP address from SonicWALL A?
This is a possible cause, because I have knowledge from Cisco, but my point of view, this is not able to communicate.
Another question: I created two static routes from both SonicWALLs with LANs connected to them, and traffic from SonicWALL A's LAN is able to ping. On the other hand, traffic from SonicWALL B's LAN is not able to ping.
I believe this is because of the encapsulation. Can someone confirm if this is the problem?
These are the statistics from both rules in SonicWALL B:
LAN A TO LAN B
On the other hand, the rule in reverse flow shows Rx statistics flowing well.
#14 LAN > LAN 14 Change priority... 130.0.10.0 X0 Subnet Any Allow All None Enabled Enabled
Access Rule #14 - Traffic Statistics
Rx Bytes: 1000285
Rx Packets: 3744
Tx Bytes: 298962

LAN B TO LAN A
These are the statistics, but it didn't work, the Rx bytes are still in 0.
#LAN > LAN 13 Change priority... X0 Subnet 130.0.10.0 Any Allow All
Access Rule #13 - Traffic Statistics
