assuming they are not behind a CGN whitelisting your mates place should be OK. But I would also move SSH away from a well known port. In the event something happens to the whitelist, crawlers will not jump on you straight away.
so just change ssh to like 137/TCP?
22 isn't forwarded
Might throw some off but that is NetBios and things will totally go for that because Windows is terrible for security.
All my stuff avoids anything below 1000 or that ends in 22 because most people will just go 2222 or 1022. pick a random number between 1001 and 65000
the server is hosted on Ubuntu server, but I'll keep that in mind
Use unprivileged port numbers for your services.
