I want to be able to access my home network using VPN (preferably OpenVPN). The problem is that port 1194 is blocked by my current ISP and the only other ISP available does the same thing. The router is a DLink DWR-921; I connect to the internet via GSM (4G).
Are there any options available? Could I use a non-standard port that's not blocked? Will this have any impact? The VPN server would be a Synology DS414.
