Firmware v4.0.4.02 has a nasty bug in the VPN section. If you switch to "IP by DNS Resolved" (yes, it says "Resolved" instead of "Resolution". Gotta love all the Engrish in the RV042!), it will automatically populate the field with "@yourdomain.com". This will cause the VPN to not lookup the proper IP address. Simply deleting the atmark after it populates will fix the problem.
Hey Cisco! How about hiring some unemployed Americans to write your firmware? It really looks BAD with all the broken English!! Almost as bad as how poorly written the HTML is. I've seen high school kids do a better job!!
Look! OMG Standards!! --> http://validator.w3.org
Let's see what happens when we validate a Cisco RV042 webpage:
