When there is a connectivity problem with one or more routers, you’ll see messages similar to these:
Here are some steps to troubleshoot and solve your router connectivity issue:
Ping vpn.zima.cloud from the router
In Winbox, go to: Tools / Ping
Ping To: vpn.zima.cloud
Latency should be <500ms.
If DNS is not resolving check the default route and DNS.
In winbox, go to: IP / DNS
220.127.116.11 and 18.104.22.168 IP addresses are for Google Public DNS.
You may set other DNS too but those work.
Ping vpn.zima.cloud again to test. It should be working and your router is connected again.
2. Check Firewall rules
To start fresh, go to IP/Firewall and remove all rules that are labelled default configuration.
Or you can adjust existing rules to allow access from 10.214.0.0/16
If you are using DST-NAT, look for rules with Dst-Port same as API (default is 8728) and make the following change:
- Dst-Address = [!] 10.214.0.0/16
3. Routing Protocols
Check your routing protocols and remove any entries in the 10.214.x.x range:
- Routing > BGP > Networks
- Routing > RIP > Networks
- Routing > OSPF > Networks
- Routing > OSPFv3 > Area Ranges
To verify your configuration, go to IP > Routes and make sure 10.214.0.0/16 is accessible only via ZimaVPN.
