Hi, I'm trying to use a NetGear R6300v1 as a VPN Router with the latest DD-WRT build I could find (dd-wrt.v24-36330_NEWD-2_K3.x_mega-R6300). I can establish a TCP/443 connection to AirVPN (using DE or NL servers) and everything is fine in my opinion: There seem to be no DNS leaks and when the VPN goes down the R6300v1 stops traffic over the WAN interface, just as I want it to. With my 100/40 MBit/s NetCologne DSL @ home I see about 15/13 MBit/s VPN Performance on the R6300v1 with TCP, I have not yet seen more than 30% CPU usage on the R6300v1 during Speedtests. Streaming 1080p YouTube videos in a browser window on a PC connected via LAN to the R6300v1 the CPU usage stays below 15%. Streaming 4K video to an iPad connected via 5 GHz WLAN results in 25% to 35% CPU usage on the R6300v1. This is using a TCP connection - I wonder if UDP would give me more performance and if I should strive further to get that up and running? My problem is: With the very same settings - AFAIK I don't have anything TCP exclusive in there - just switching to UDP for connecting to AirVPN I cannot browse anything anymore. DNS resolution still works with UDP, I can ping for example www.heise.de both in Windows and via SSH directly on the R6300v1, I just cannot browse to www.heise.de. On a sidenote, the same is true if I use 'OpenVPN connect' on an iPad (iOS 11.4.1) - when I generate a .ovpn config for TCP/443 to German servers all is well, same config just with UDP/443 not so much on the iPad, too. On a second sidenote, I can get the latest Tomato build I could find for the R6300v1 (tomato-Netgear-R6300V1_RT-AC6x--140-AIO-64K) to do the same and have the same UDP issue as with the DD-WRT load ... I settled for DD-WRT for now because it seems to me the hardware support, especially WLAN AC, is better in the more recent DD-WRT build I'm using. I think I'm either missing something obvious or UDP simply cannot work on the R6300v1 (and an iPad). If anybody has an idea what I should try differently with the settings, I'd very much appreciate the information. Thanks in advance, Kyle
