Minor problems upgrading ROS from 6.49 to 7.10

Wed Aug 16, 2023 2:58 pm

I debated about this upgrade for a long time and the need for Wireguard to replace a PPTP vpn on a pair of simple home routers(two physical locations) won out. I believe in not fixing what ain't broke but Android and IOS are making it difficult to use pptp.

It (7.10) installed and it(wireguard) is awesome. I can access all the services I need to (rdp/smb/winbox) from remote android and windows.

I am left with a couple of nagging issues maybe someone can help with:

1. There is some pptp and l2tp detritus in the /interface section of the config file that I can't make go away. I've checked under interfaces in winbox and via print and there is nothing related actually there. Probably not important but it's annoying.

2. Although I could update from 6.49 to 7.10 through winbox system/packages/check for updates without issue now, under 7.10, when I checked to update to 7.11 I get "ERROR:Could not resolve DNS name".

3. I have done an external port scan and everything looks locked down but I am new to Mikrotik from a lifetime of consumer routers. If anyone knowledgeable can take a quick squint at my firewall section and tell me whether or not there is anything obvious I should do differently or better that would be very helpful.

Thanks much.
