Hi Folks,

i have the following job to do:

Connect a branchoffice to the headquarter using a 2Mbit dsl-line with a vpn.
so far, so good, but what we want, is to ensure, that a certain amount of
the bandwidth is guaranteed for the use of rdp-connections and other
services (ipprint, ftp..) may fight for the rest. that means, s.th. like qos
within the vpn-channel. any ideas how to implement this ? which hardware is
cappable of doing this? do i need software? or is it simply impossible?

thanx

torben

two options - buy a VPN firewall/router that has bandwidth management,
or (simpler IMO) buy whatever VPN hardware you want and the stick a
"standerd" router (ie: cisco, nortel/bay, juniper, etc) that does
diffserv between the firewall and lan on each side, so that all packets
go thru the routers before going out over the VPN. The qos gets handled
by the router which then send the packets on out to the VPN. More
expensive that way, but less headache in my experience.
