Ok guys Linksys has given me authorisation to release this as a beta. The main difference is the firmware now supports Multiple Subnets from network page. RV042 Firmware v188.8.131.52 Release Note New Features: 0. Support multiple subnets when RV042 is in the Gateway mode, i.e. NAT enabled. Now users can specify multiple subnets on the Setup->Network page. 1. Support Paid Custom DNS for dyndns.org. A Custom DNS checkbox is displayed on Setup->DDNS->DynDNS.org page. 2. Support IPSec NAT Traversal in both Gateway-to-Gateway and Client-to-Gateway modes. Issues Fixed: 1. Fix the "Selective Acks Off" issue that affects performance. 2. Fix the issue with saving a pre-shared key with apostrophe. 3. Fix the subnet mask issue. Remark: In previous firmware, when the router's subnet mask is set to 255.255.255.192, 255.255.255.224, 255.255.255.240, 255.255.255.248, or 255.255.255.252, you will no longer be able to change the subnet back to 255.255.255.0. 4. Restrict the Dynamic IP Range in DHCP Server Configuration to be in accordance with the LAN IP and Subnet Mask configuration of RV router. For Example, when LAN IP/Mask = 192.168.1.1/255.255.255.128, the DHCP IP Range the user can configure will be restricted to the range of 192.168.1.1 through 192.168.1.126. 5. Fixed a PPTP Server problem that failed to establish PPTP connection when DMZ Host enabled. 6. Disallow users to set x.x.x.0 in the LAN IP address field. 7. Update the on-line help of VPN Client Access (QuickVPN) Setting. 8. Modified the alert message as the following when enabling Remote Management. (1) When https is enabled, remote management enabled, and password being the default password, Message: The Router is currently set to its default password. As a security measure, you must change the password before the Remote Management feature can be enabled. Press "OK" to change your password, or press "Cancel" to leave the Remote Management feature disabled. (2) When https is disabled, remote management enabled, and password being the default password, Message: Please be warned that once remote management is enabled, it will be safer to remotely administer the router by https on port 443 instead of http. The Router is currently set to its default password. As a security measure, you must change the password before the Remote Management feature can be enabled. Press "OK" to change your password, or press "Cancel" to leave the Remote Management feature disabled. 9. RV042 will listen to ports 443 and 60443 for QuickVPN connection. Remark: Earlier firmware only listens to port 443. Known Issues: 1. Changed the DHCP Server implementation. When the DHCP client requests the IP address of DNS server, RV042 will offer the DNS server's IP address obtained from ISP. (In previous firmware, RV042 offers its LAN IP as the DNS server's IP address.) However, if users configure a DNS server in the LAN and specify the IP address of the local DNS server on the Web UI, RV042 does not offer the local DNS server's IP address to the requesting DHCP clients. **If firmware upgrade should fail using the Web UI, a TFTP utility can be used to load the v184.108.40.206 firmware into the router. You could then upgrade the firmware to v220.127.116.11 using the Web UI.** Download is avaible here: http://www.linksysinfo.org/portal/forums/downloads.php?do=file&id=28 Discussion of any relevant problems this firmware should be done in this thread in this thread. if you have a bug, please give as much details as possible of how to replicate the problem, and what methods you have tried to fix it.
