I agree do not commit without POC or trial bases.

No NAT. Reliability? Best effort at best. Coverage area is ok. Speed and reliability is completely dependant on your location. Test first. Always. And then do not set a decent expectation. IPSec tunnels dropping? Could be. Again, depends on your locations. My overall impression? Get a T1. My overall recommendation? Complete site surveys and then have a back out plan. tv ----- Original Message ----- From: "Crooks, Sam" <Sam.Crooks@experian.com> To: <nanog@nanog.org> Sent: Tuesday, April 14, 2009 11:25 PM Subject: Looking for AT&T / Verizon / Sprint WWAN service impressions - on oroff-list replies welcome I'm considering use of AT&T / Verizon / Sprint WWAN services and the Cisco 3G router interface cards/integrated module in C880 routers for primary or backup WAN network connectivity for routers. I'm looking for information from users of these services on the following: - addressing - Do these WWAN services use dynamic, PPPoE or static IP assignment typically? Any of the 3? All? - is static IP assignment available? - do these service providers use NAT within their network? - How is the service reliability? In most cases, is the service available for use when you need to use it? - How is the service coverage area? Do you have problems getting sufficient coverage in the deplouyment location to support desired speeds (say 512kbps up/down as a minimum)? - is ESP / IKE / IPsec permitted through un-rate-limited and un-molested by the providers? - If you build a IPsec/GRE tunnel over these services, do you have frequent issues with the tunnel dropping, or a dynamic routing protocol running through the tunnel going down frequently? Also interested in similar information on impressions of similar EMEA WWAN service providers, particularly Vodaphone and T-Mobile, if anyone has experiences with these. Replies on-list or off-list are welcome.... Your choice.
