Hi there !

I have two working setup for a VPN tunnel into my company LAN. Basically,
the two options for a laptop are:

1. VPN-Client - WLAN - *

2a. WLAN - PowerLine - C1710 VPN - PowerLine - *
2b. FE - C1710 VPN - PowerLine - *

both        * - DSL router - 6/1 line -- IN -- E1 - PIX 515

Option 1 feels ways faster. At a first look, the double PowerLine piece
seems to be the culprit but it should still be faster then my 1 MBit uplink
and the E1 links.
IIRC, the connection is faster on another machine (2b) using the PowerLine
only once but I haven't tested it lately. This may blame the PowerLine
again but what about the performance of a 1710 (VPN module installed) in
this context? Can the router be the problem?

I'm planning to replace the consumer DSL router by a 1841 soon. The VPN
tunnel will also terminate here. I think I can expect a better performance
then?

TIA
