replace VPN with wireless bridge David Kirchner 01-24-08

I have 2 locations with linksys RV042's. 1 with cable internet at WAN1
and 192.168.1.1 at LAN. 2nd location has DSL at WAN1 and 192.168.2.1
at LAN port. The VPN traffic is too much for my internet
connections. I now have a wireless bridge between locations. I have
set both RV042 as Dual Lan with WAN2's with the extra static IPs from
my DSL line and was able to VPN from WAN2 to WAN2 over wireless
bridge, but I am not seeing the throughput I can get just testing over
the bridge. I have opened the bandwidth management to max and bound
protocols like 25,80 to only use WAN1's.

Throughput numbers from IXIA Qcheck;
VPN Internet -WAN1: 0.4Mbps
VPN Wireless-WAN2: 2.4Mbps
Wireless bridge only: 5.4Mbps security is WPA-PSK(AES)

I wander if the RV042 is not able to calculate VPN as fast as my
wireless network.
I have tried the WAN2's as DMZ (192.168.10.*) and VPN between
locations, but I could not figure out how to use a static route
instead of VPN?

I next tried location 1 as single WAN/DMZ, with no DMZ(0.0.0.0). I
plugged location 1 wireless bridge to the LAN traffic (192.168.1.0).
At location 2 I plugged wireless bridge into WAN2. The RV042 at
location is set to dual WAN,Load balance. WAN1 is DSL, WAN2 is
192.168.1.92 255.255.255.0 and LAN is 192.168.2.1 255.255.255.0.
Location 2 could get to Location 1, but Location 1 could not get to
Location2! I tried ROUTE on location 1, 192.168.2.0 255.255.255.0 ->
GW 192.168.1.92

I was able to use the RV042 Diagnose Ping tool- I could ping any
address from either location but a ping from a pc on either side would
not work. The log shows as connection accepted, but ping still timed
out.

I am not sure the RV042 is going to work for me. Anyone ever use a
RV042 for this? What other cheap equipment can I look into that:
1 I can have Internet local to each network. I do not wont to send
http junk across my wireless bridge!
2 I can have 192.168.1.0 network work with the 192.168.2.0 network
over my wireless lan.
