Try flashing the RV042 with the latest firmware (4.0.4.02)

http://www.cisco.com/cisco/software/release.html?mdfid=282414010&softwareid=282465789&release=4.0.4.02-tm&relind=AVAILABLE&rellifecycle=&reltype=latest

Note that it is likely that the RV042 contains a version of freeswan or
older openswan. You might be able to make a custom firmware with upgraded
openswan on it.
