Hi,

 

How/where could I enable GRE passthrough (or PPTP passthrough) on ER8411 standalone?

 

I was looking both in firewall section and vpn section but there is no such explicit option, or I did not find it.

 

Thank you,

GRE does not support ALG.

GRE with IPsec, IPsec supports ALG. 

 

PPTP ALG is supported and enabled by default.
