The VPN gateway was moved behind the Internet router and now the remote devices cannot access it.
When it is said open port, does this mean opening traffic from outside(internet) going to inside(LAN/VPN gateway)?
Are we going to do an IP NAT SOURCE STATIC to all the mentioned ports above to the IP Address of VPN gateway?
About access list, which router interface should we apply this one? and is it INbound or OUTbound?
many many thanks.
