have a strange issue with network.
I recently merged 2 sites together, updated default gateways and one device does not respond. It only responds on the old VPN connection.
Site 1 <--> Site 3 - previously commissioned, connected via VPN via internet connection to the site
Site2 new commission merged with Site 3
Site 1 <----> Site2/3
Everything on the old site (3 devices) had there gateways updated to the new router, 192.168.103.1 and 2 out of the 3 devices work.
Black Box: Sites
Green Box: Company Owned Equipment
Orange Box: Vendor Wan (Untouchable)
Red Box: Problematic Device
Site2 Gateway: 192.168.103.1
Site1 Gateway: 10.10.5.52
Server1 <-->Site2/3: Gateway = 10.10.5.52 for network 192.168.103.x
From Server1: i can ping everything, except the problematic device, 192.168.103.20
From Server2: i can ping everything from the OLD VPN that i want to disconnect (Unreliable connection)
From Server2: I can ping everything on the new WAN except the problematic device, Similar to Server1
From the 192.168.103.1 router, i can log into it and ping the problematic device. Its been rebooted. No resolution.
Strangest Issue: SOMETIMES, ONLY SOMETIMES, you can get few pings from the problematic device on the new WAN, but then stops responding?????
What can the issue be?
