5.6 VPN Passthrough for Firewall
Advanced > Firewall Settings > VPN Passthrough
This router‘s firewall settings can be configured to allow encrypted VPN traffic for
IPsec, PPTP, and L2TP VPN tunnel connections between the LAN and internet. A
specific firewall rule or service is not appropriate to introduce this passthrough
support; instead the appropriate check boxes in the VPN Passthrough page must be
enabled.
