our locable provider ships Motorola SB 5100 and SBG 900, the latter one for customers who want WLAN. To my surprise, the SB 5100 does NOT force you into Routing/NAT (as many ADSL modems/routers do nowadays), but behaves quite transparently: It just talks IP over Ethernet like a bridge to another LAN would do. So if only you hook up a single machine, you're directly connected to the Net and IPsec works perfectly fine.
My question is: What does the SBG 900 do, especially for WLAN clients?
- Does it have a of 'bridge mode' so you could do WLAN without NAT for a single client?
- If you do NAT, will the IPsec passthru feature mentioned in the manual work with a Cisco VPN connection? We have a Cisco 3030, and there are frequent problems with users doing NAT on some ADSL modem/router.
Thanks for help Martin
