Supernetted network, can't access devices on PC's

I have a network 192.168.0.0/23 set up and have a phone system running on 192.168.1.25. I can ping the phone system from the router, but not from my machine which I am currently VPN’d (PPTP) in on using 192.168.0.48.

Any ideas?

check if the subnet on the machine is correct

255.255.255.255

I am using a PPTP connection.

I had the sam problem awhile ago where i pptp into network and could not access devices on that subnet.
What i did was to add nat rule.

/ip firewall nat add src address(pptp local address on router) action masquerade.

Hope it helps

No luck. It seems my phone system on 192.168.1.25 can ping a 192.168.0.x address. I really have a hunch it’s the PPTP connection not working right.

Is proxy arp enabled?

Proxy arp is enabled on the bridge-local

Can you ping the router when connected with vpn?
What does your computer show when you try to traceroute to the phone and to the router?
Have you setup /23 network on both sides?

If I am on a 192.168.1.x address, I cannot ping the router, only the phone system, with tracert,
