I recommend Lantronix boxes for the ST (and they work ok for the 8-bit too, providing you have an 850/PR/etc. but you'd need that for the WiFi232 as well).
There are a lot of threads on the 8-bit forums about them (including details on how to set them up).
That's what I use for both SFHQ and TVAG BBS's
The problem with the Lantronix is that it's quite a bit more complicated to get it to work. You have to download Belarc Advisor and PuTTY. I tried this two years ago, and I was never able to find out what my router's IP number (the one assigned to the Lantronix device) was with Belarc. Therefore, I was never able to get the proper setting in PuTTY. I tried multiple IP addresses, and nothing worked.
Perhaps it was my crappy then-Time Warner router, but I gave up after looking for help and not finding a solution.
