I've already switched providers once hoping that thew new provider would not block 5555 but with no luck. I even made sure the new provider was on a completely different network, hoping that might increase the odds of the new one working (old provider was on the Verizon network and the new provider is on the T-Mobile network).
While I do like to play on the go, this is mostly for cases where my home or work internet goes down while my PC is out and about. I like to be able to log in before the disconnection protection timer expires and at least get my PC somewhere safe.
This used to be manageable with VPNs but Sindome, understandably, does not want us connecting via VPNs. I could setup a SSH server on my home system and use it as a jump box or port redirect to log in but this is pointless when my home internet is out.
Perhaps I am just very unlucky in providers. I have connected to other muds with these providers on other ports like 7777, 4242, 1280 and even 23. I am not sure why they hate 5555. Then again, maybe others also experience this issue?
