Hello,

I have Mikrotik in my office. At home I'm running Asus, which is OpenVPN server. There is public static IPv4.

I was able to import ovpn config to Mikrotik and it looks connected: My office network created by Mikrotik is 192.168.88.x and home network is 192.168.50.0. Routing table on Mikrotik: Problem is ping from Mikrotik to 192.168.50.1 (or any other device in my home newtwork) ends with timeout. I'm trying it from Mikrotik > Tools > Ping.

Maybe I need to setup firewall on Mikrotik somehow? Can somebody help me with it please? Thanks

Maybe you should allow port 1194?

Try to ping Mikrotik from Asus and allow icmp input. Does it work?
If it does, then problem is a firewall on the Asus.

I am pretty sure you must open firewall on Asus and configure routing there
