Issue connecting with VPN

I have searched the forum, and I am not sure if I did not see it, or I am not knowledgeable enough to know what I am looking for.

Here is my situation. I have a RB951G Mikrotik. I have setup a VPN so I can connect my laptop to my home network when I am away. My home network is 192.168.15.x

I have been able to create the vpn in the Mikrotik. When I go to another internet location, I can connect to my home VPN. According to ipconfig, I get an IP address of 192.168.15.20, a subnet mask of 255.255.255.255 and a default gateway of 0.0.0.0

I can ping the router (192.168.15.1) and can even log into the router using Winbox via the VPN, but I cannot ping or access anything on my network (example, I cannot ping 192.168.15.104).

I will be happy to provide any information that may be needed to help diagnose this issue, but please be patient, as I am still learning.

Thank you in advance for your help.

I found my solution. I followed the directions here:

and my issue was my ARP setting. Once i set it to proxy-arp instead of just enabled, that fixed it..
