Please, I need some help... I'm trying to connect two RV042 devices back2back using VPN - but I just can't get it going. The setup (both running 188.8.131.52 firmware): PC#1 - 192.168.1.0 - RV042#1 - 192.168.4.0 - RV042#2 - 192.168.2.0 - PC#2 RV042#1: - LAN port config: static ip: 192.168.1.252 sn: 255.255.255.0 gw:192.168.1.254 - WAN1 port config: static ip:192.168.4.1 sn:255.255.255.252 gw:192.168.4.2 - firewall enabled, router mode - vpn tunnel gw2gw mode - local group: ip only, ip addr 192.168.4.1, subnet, ip 192.168.1.0 - remote group: ip only, ip addr 192.168.4.2, subnet, ip 192.168.2.0 - IPSec: factory default (IKE preshared key) RV042#2: - LAN port config: static ip: 192.168.2.252 sn: 255.255.255.0 gw:192.168.2.254 - WAN1 port config: static ip:192.168.4.2 sn:255.255.255.252 gw:192.168.4.1 - firewall enabled, router mode - vpn tunnel gw2gw mode - local group: ip only, ip addr 192.168.4.2, subnet, ip 192.168.2.0 - remote group: ip only, ip addr 192.168.4.1, subnet, ip 192.168.1.0 - IPSec: factory default (IKE preshared key) Now, at the VPN summary page on both, the status is 'waiting for connection' On #1 I hit connect, wait until the button reappers (status is still 'waiting for connection'). Checking the VPN log, the initial VPN message has been send a few times, then... nothing. Checking the VPN log on #2, nothing at all has been received. I turned off the firewall on both, then on #1 I went to the diagnostics page, to ping the other wan port - no packets got through. Also tried from #2 - with the exact same result. Should I not be able to ping the WAN port from the diag page, when firewall is disabled? I've tried any possible combination of the 4 RV042 devices, I have at hand - same result. I've tried to replace a known working internet gateway device with each of the three others - I doesn't look like any of the devices are in a non-working condition. I've tried to restore the configuration to facory default, using the web interface and the reset switch. Then configured from scratch. I've tried to reset, switch on/off power. I've tried just about anything I can think of. All with no success. This VPN issue has puzzled me for almost a day now - I just can't believe it can be that difficult! Please... anyone... suggestions are very welcome.
