From the Linksys.com site: Troubleshooting Linksys QuickVPN Connections Router Settings These settings, which can be found in the web-based Setup utility of your router, should be configured to allow QuickVPN connections. Host Name: <should be left blank> Domain Name: Should be filled in with any domain name followed by .com, .net, .org, etc. (for example, mylinksys3.com). The domain does not have to be a valid domain that exists on the Internet. Without a domain name, you may get an "ERROR: malformed status line -1" entry in the wget_error.txt log file (found in the \Program Files\Linksys\Linksys VPN Client folder) MTU: An MTU value of 1428 can be used and decremented further to test. HTTPS (RV-series VPN routers only): Should be set to Enable. Port Forwarding: Ports 443 and 500 should not be forwarded to the LAN. These well-known ports are used to create the secure IPSec tunnels used by QuickVPN. DMZ: DMZ (De-Militarized Zone) features should not be used. QuickVPN Client user accounts: QuickVPN Client user accounts need to be set (checked P) to Active. ============================================ So has anyone gotten QuickVPN working reliably when using the DMZ as well on the RV0XX series? Personally, I use an RV042 and we've been having a terrible time trying to get the VPN working even after following the stickies here.
