Hi. It appears that you want to set up a L2 VPN with PepVPN or SpeedFusion. As it happens, there has been a fair amount of discussion here about how to do that. Not difficult. See, for example:
Setting up a Layer 2 PepVPN Profile in Firmware 6.2 Onwards. @MartinLangmaid, in particular, has discussed this a number of times here.
Suggestion: Try the link above and see if it’s any help. If you get stuck let us know!
