Point to Point - Layer 2 connection between two firewall

[Pushpaksinh]

Hi, 

I am trying to establish Layer 2 connection between two firewalls at different locations.

Location 1-(HO)

Wan 1 - internet

Wan 2 - internet

LAN 3 - internal network

LAN 4 - Vlan 300 - 10.255.255.1/30

Location 2-(branch)

Wan 1 - internet

Wan 2 - No connection

LAN 3 - internal network

LAN 4 - Vlan 300 - 10.255.255.2/30

So LAN 4 is connection between between two firewalls.

1)What will be the configuration to utilized internal network connection between two locations?

2)And if WAN of location 2(branch) failed, is there any way to utilized internet of location 1(HO)?

I think this link by @alemabrahao would best fit your use case.

Actually I want 2 tunnel at a time,

1 is P2P for internal communication

2 is Auto VPN(backup)

the issue is not with backup auto VPN and solution link by @alemabrahao .

the condition is at branch , WAN 1 will be utilized for internet and LAN(p2p) will be for internal communication.

however if WAN 1 fails, LAN will provide internet to branch via P2P.

Even Meraki tac has suggested link same as @alemabrahao  but my requirements is not satisfy with that configuration.

Unfortunately, the only way to use L2 as a backup is to use it as a failover.

I did this for an organisation and the model I followed had the branch VLAN 300 on a WAN port.  The HQ MX was in VPN concentrator mode with a L3 switch terminating VLAN 300 and a separate set of firewalls as the corporate edge.  After leaving another team thought they could simplify it and maintain functionality, but ended up realising that it was the only sensible way to get it all working.
