Some IP's are starting to stop working over VPN but work fine over local LAN

Fri Nov 30, 2018 8:26 pm

Hello,


our network is a 172.19.0.0/19

our VPN DHCP Pool is 172.19.3.2 - 10



we are starting to get a short handful of (all have been in the static pool) IP's that will not let you access them over VPN


Acts as if the there is an IP Conflict but if I change the IP on the device there is still nothing pingable to the old IP and not finding any lease to it


Does anyone have any ideas on this?

1 The device is a Mikrotik 950 works fine locally but I can't get to it over VPN

other devices are UBNT


Thanks for any help

You should not use same subnet for VPNs and LAN.
The poor ARP tablet is going to find your VPN clients in LAN.
Use different subnets and route/NAT to make them talk.
