We've used mikrotik routerboards that support ev-do as wireless serial adapters.. It is only good for a single port application.. but it works.. and at a price of $99.. it would certainly support access lists.. we have them dial back to a pptp concentrator... just a thought..

Avocent / Cyclades boxes have ACL capability (they run Linux) and can be used with EV-DO/GSM modems. They may not be the lowest cost solution, but there is a central management system and a wide range of serial interface units from single port to at least 32 ports.

Can anyone recommend a cheap Ethernet to Serial (RS232/422/485) converter with functionality like the Lantronix boxes .. except one that supports access lists (nothing complicated .. maybe a list of 5 approved hosts). I need a bunch of single port devices, not an access-server for a rack.

We use SENA PS110 boxes ( http://www.sena.com/products/device_servers/hd_ps_x10.php ). They work very well, have various ACL features (dunno if it supports 5 named IP or >not), and other configurables.

On a similar topic, any good solutions for out-of-band serial console/Ethernet solutions that use EV-DO/GSM wireless Internet?
