==============================================================
Site 1 = Cisco ISA 500. Named as CHI
Site 2 = Cisco RV042. Named as Alabang
Shown above is the logs from my ISA 570 IPSec VPN. I have set the same settings for my IKE Policies and my Transform Sets. Attached are the screenshots of my the VPN Settings of my 2 systems. It does show in the table above that the 112.209.172.XXX is unreachable, but please look at screen6.bmp and see that I can very well ping the RV042 system. Please feel free to ask me for more info about my setup.
On a side note, take a look at Screen5.bmp. This screenie shows that I have an existing WORKING VPN connection to another site with a Linksys RV042, named as Villa. So as you can also see in the screenshot, it has a VPN setup for CHI but it can not connect. Hence my problem above. The VPN setting for Villa is the same as CHI (PFS, IKE, Transforms, PFS).

Answer 1

Dan,
Since I'm not a Cisco employee, don't have access to spare ISAs and RVs to setup a lab and test, don't have a setup similar enough to yours to test with, don't have access to your devices, and wouldn't have other than UI access if I did, doing a little trial and error is all I have to work with to assist you.
That said, it's not random trial and error. From what I'm able to see via your screenshots and explanations, all of your config looks correct. So if everything for Phase 1 & 2 are accurate, then it should work unless there is an interesting traffic mismatch.
Usually this is pretty straightforward and simple to troubleshoot and confirm. However when you add in additional challenges that come with Multi-WAN support, terminating the VPN on the secondary WAN interface, and PBR, there is a lot of room for possible mistakes as the config is becoming fairly complex.
So my thought was to remove what I perceived to be the least impacting piece of complexity, which is the custom PBR that is sending those 2 laptops out WAN 2 instead of WAN 1, so that the only non-typical configuration was the VPN terminating on WAN 2.
Right now I'm assuming the issue isn't the the possibility of the ISA and RV042 being incapable of establishing a VPN. I'm assuming it is either an issue with VPN termination on WAN 2 (which I don't believe is an issue) or something not quite right with PBR and VPN interesting traffic.
