Dial-in IPSec VPN assigning wrong netmask. was created by undergrid
I have a Vigor 2860 configured to allow dial-in IPSec VPN access to my home network. The home network is 192.168.0.0/22 with DHCP turned off on the router and supplied by a Raspberry Pi running dnsmasq.

On the router, the PPP General Setup page has "IP Address Assignment for Dial-in Users (When DHCP Disable set)" configured to 192.168.2.10 and this is indeed the assigned IP address. However I am getting 24 netmask (255.255.255.0) assigned rather than a 22 (255.255.252.0) which means anything outwith the 192.168.2.0/24 address set (everything in 192.168.0.0/24 and 192.168.1.0/24) is unreachable. Is there any way to fix this?

Thanks.

If you go to LAN >> General Setup >> Network Configuration can you confirm your Subnet Mask in here is set to be 255.255.252.0 and not 255.255.255.0.
