I have 5 VLANs configured on my 1350, all of which where working just fine until two days ago.
VLAN 10 is configured as 192.168.1.0/24 with the gateway as 192.168.1.250, one of our partners connected to the Peplink via a PPTP session and their LAN range conflicted with VLAN 10.
Since then, machines on VLAN 10 cannot get to the outside world, but can ping other clients on the same VLAN, I also cannot ping the gateway address.
All other VLANs are operating normally
The problem seems to lie within the peplink, is there anything I can check / do to get things working again?
As an aside, if I change the VLAN IP range to say 192.168.10.0/24 it works as normal, just not with the 192.168.1.0/24 range that worked previously.
