Hello there.
I am having issue connecting to an outside IKEV2/IPsec VPN server from my local pc. I have a TP-Link Archer C7 v2 running OpenWrt 19.07.3. If i use my hotspot or any other connection it works just fine, so i believe its something to do with OpenWrt settings. I am using default settings on the router. Any inputs would be highly appreciated.
