i'm running VPN which is IKEv2 and with the ip address from modeconf (HQ) i'm running IPIP tunnel.

Everything works fine i mean the tunnel and everything.

I've just seen that when i'm accessing from the HQ side to the BRANCH office on ipip-tunnel adress i heve (see picture-and after min im lossing the connection), but when im accessing on any ip adressess on this router,everything works fine.

im wondering why it comes like that...i can ping the ipip-tunel ip.
Only happens when i'm trying to get access via winbox, SSH works fine
