Question

VXLAN - different VLANs ?

Hello I want to configure a L2 VLXAN over IPSEC tunnel.

Previously I have had this working with multiple VLANs that entered the Fortigate via tagged sub-interfaces (TRUNK interfaces from my switches).

However, this time, I have a single VLAN environment on both sides (ACCESS switchports connecting to untagged interfaces on my Fortigates), but that single VLAN is tagged differently on both sides e.g. SIDE_A=VLAN 10 & SIDE_B=VLAN 20.

Therefore I need traffic entering SIDE_A Fortigate as VLAN 10 to exit SIDE_B Fortigate as VLAN 20.

Is this possible at all ?

Hello,

 

Thank you for your question. It should be possible. I've never explicitly tested this scenario, but it shouldn't matter that on FGT1 in software switch will be VXLAN+VLAN10 and on FG2 VXLAN+VLAN20.
