Maybe I just go to different sites than you, but I run into problems accessing web sites from AirVPN fairly often. Its also possible that the AirVPN servers that you use are not blocked like they are for mine (Chicago, Atlanta, Miami, etc).
Like I said above, the best thing is to try any VPN service for a few days or a week to see whether anything annoying happens in your use case before jumping into a long term contract.
I don’t know really anything about network setup, but as far as I know, your ISP should have nothing to do with it while you use a VPN.
All I had to do was change the settings on the AirVPN account on their website (logged in) and add the port to my qbittorrent settings. This is unrelated, but I also added a killswitch in qbittorrent advanced settings that stops torrenting if my vpn connection fails. After that, I went to a site like https://canyouseeme.org/ and verified my port forwarding was set up properly.
I never had to touch my router or ISP settings. My configuration is running the VPN from each device. It is also possible to set up your VPN directly on the router. That way, all traffic on the home network is through the VPN.
I use AirVPN. It’s reliable and I like their vpn client Eddie, but there are a few things you should know. Google blocks traffic from all of their Dallas servers, about 20% of their us based servers. Also, a few web hosting companies block AirVPN traffic, at least on the servers I use, including GoDaddy. I can’t access the Linux Mint forums while on AirVPN either. Every day or two I have to disable the VPN to access a site, which defeats the purpose, IMO.
One good thing about AirVPN is that they have sales often. But I would try a week now before committing. Reliability has been top notch and they have a lot of servers.
Edit: I use port forwarding for bittorrent and it was easy to set up. You log in on their website and choose a port to forward for your account. I’m honestly a novice at networking and I figured it out using these instructions.
Yes, GoDaddy is a very popular hosting company. I would do a short trial on any VPN before committing to a longer contract. It is possible that the sites you visit won’t block your geographically local airvpn servers. Web hosting companies treat different servers from the same VPN differently.
