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. RV016 Firmware v2.0.13 Release Note New Features: 0. RV016 in the gateway mode now supports multiple class c subnets, each connecting to the LAN of RV016 through a router. To use this feature, administrators need to specify the multiple subnets in the Setup->Network->LAN Setting page of the Web UI. 1. Support Custom DNS, a paid service provided by dyndns.org. A Custom DNS checkbox is added to the Setup->DDNS->DynDNS.org page. 2. Support IPSec NAT-Traversal in both Gateway-to-gateway and Client-to-gateway modes. 3. RV016 will listen to ports 443 and 60443 for QuickVPN connection. Remark: Earlier firmware listens to port 443 only. 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. Fix 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. Fix an issue with enabling IPCompress (IPComp). 8. Update the on-line help of VPN Client Access (Quick VPN) to explain the two versions of firmware of RV016. The default version supports 15 QuickVPN clients; the q50 version supports 50 clients. 9. Add "linksys.com" as the default Domain Name and leave Host Name to be blank after reset to factory default. 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. http://www.linksysinfo.org/portal/forums/downloads.php?do=file&id=30 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.
