We have some users who often work from home and in general there home ADSL internet connection is reliable however there are times when there connection is temp down. These users rely on being able to access email and network resources anytime by connecting to our VPN (sonicwall hardware VPN box)
Id like to setup an alternative or backup option for the most critical users so that they can still access network resources and email should there internet connection fail but im not sure which internet backup solution to use.
I thought perhaps 1) setting up a dialup RRAS connection, and installing some external modems,
but this could be to slow epecially when downloading larger files, and not sure how reliabe setting this up in sbs 2003 is?
or 2) alternatively getting some mobile broadband USB modem sticks that seem to be getting ever more popular. but im not sure how reliable the speeds are? - does anyone know how reliabe the speeds are?, as in areas where 3G is not avaliable most providers divert to GPRS which is much slower.
i thought maybe using vodaphone or T-mobiles mobile broadband service.
Any advice or alternative solutions would be great
