How to create a trunk between my Sophos Firewall XG X3300 and my Watchguard M410 ?

Hi Tovo RAKOTOZANANY ,

Good day and thanks for reaching out to Sophos Community, hope you are well.

Would the Watchguard M410 be retain in the setup? If yes, does the interface eth1 of WG->XGS Port2 be a routed/L3 interface? 

If yes, you would likely need static routes from WG (default static route) and XGS to WG (static routes) to introduce VLAN networks. Kindly note as well that if WG would have a routed interface going to XGS that traffic would likely be NATed from WG and you might need to plan you FW policy in XGS accordingly.

Also, since this is an implementation activity. I may recommend to consult your local Sophos partner or consider availing Professional Services https://www.sophos.com/en-us/support/professional-services

Have a nice day ahead and Thank You for choosing Sophos

Cheers,

Hi Tovo,

Thank you for reaching out to Sophos Community.

Is this one the same setup from the previous post but only Watchguard?

You may try to refer to the link given in the other post on how to set up a VLAN trunk for Sophos XG with another vendor. Kindly try to replace the Cisco setup with the watch guard configuration for trunking.
