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... 22.214.171.124 X0 Subnet Any Allow All None Enabled Enabled Access Rule #14 - Traffic Statistics Rx Bytes: 1000285 Rx Packets: 3744 Tx Bytes: 298962 Tx Packets: 3377 Usage: 451 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 126.96.36.199 Any Allow All Access Rule #13 - Traffic Statistics Rx Bytes: 0 Rx Packets: 0 Tx Bytes: 41760 Tx Packets: 696 Usage: 2
