Hi, Thanks for the pointers to the Juniper devices. I think I'm really thinking about layer2 encryption, rather than do the encryption using IPSEC. I feel that as its a p-t-p fibre link, this makes most sense in terms of throughput and least impact on the network. Operating at layer3 the IPSEC solution introduces more complexity than I would like across this link. As I understand it, with layer2 encryption devices VLANs between the sites, would "just work". I'm interested to hear of peoples experiences with layer 2 encryption devices out there, as I don't have that much experience with them. I think my subject line mentioning IPSEC is a bit confusing as I'm really after information on Layer2 encryption hardware. Adel On Wed 6:45 PM , Brad Fleming bdfleming@kanren.net sent:

Not knowing all your other needs, I won't swear to it... but would the Juniper SRX650 work for your situation? It can pass 1.5Gbps of encrypted traffic according to their datasheet. I've never actually tried to move that much data through the box so I can't testify to it.

Also, the Juniper SRX3400 is advertised as handling 6Gbps of encrypted traffic.

Of course, these are JunosES devices as opposed to ScreenOS, but the transition isn't as painful as you might expect. We actually use the J- series devices with JunosES as site routers/firewalls with a great deal of success.
