We have one 24X with a newly installed Sonicwall. It seems to be working well, now---but we did have to make some changes with DNS settings. No problems with the 15000 range ports.

We have customers with Barracudas, Ciscos and NetGears mainly. All seem to work fine---but the Netgears seem to be about 1/10 of the cost of the others. I'm sure that they don't do as much---but they seem to work fine.
