Is there any solution to getting gigabit speeds through a Netgear r7000 with dd-wrt on it?

Wired speed is getting chopped from ~950 through the ISP router to ~450 when through the dd-wrt r7000.

The r7000 is running in gateway mode. Would it speed things up to run in router mode instead since the ISP router can NAT?

Thanks!

DD wrt performs software NAT, this is CPU intensive so 450MB/s is max. The stock Netgear firmware has hardware NAT(CTF= cut through forwarding), this skips in part the firewall so it is less safe and you loose things like QOS, but it will get you close to 950MB/s.

If you want a router with DDWRT capabel of 950Mb/s you have to buy an Atheros based router like the Netgear R7800

Thank you for the quick response. If I understand correctly, I can disable NAT on the r7000 by running in router mode instead of gateway mode. Assuming I configure the static route correctly, would this make the r7000 capable of ~950 speed?

Just use it as a WAP and connect LAN-LAN and you have gigabit speed (see https://www.dd-wrt.com/wiki/index.php/Wireless_Access_Point), or use IPv6 Smile this is also not NATted.

The whole point to my adding this router and flashing to dd-wrt is so that I can connect a VPN through the router for a whole home VPN setup. If I make the router a WAP, can I still connect the VPN?

Ok, I see what you want.
First, VPN (at least OpenVPN) is very CPU intensive, this router will max out at 60 MB/s for a VPN connection.
Regarding your question is a VPN client possible on a WAP, I am not sure I have never done it.
I am using VPN on my secondary router, but it is in gateway mode (with SPI disabled). I think it can be done, if your main router is at 192.168.1.1 and you have your WAP at 192.168.1.2 with its openVPN client then you set the gateway of your clients at 192.168.1.2 and it should be routed over you VPN.

If you want to be sure ask this in the advanced networking forum there are very smart guys over there and of course the yoda of networking Smile

Whoa, I've been told there would be an overhead hit for VPN, I never imagined it would max out at 60 mb though! I've been recommended to go with the r7800 to get the atheros chipset and the faster cpu. Do you know what the max will be with VPN running on that model unit?

I guess a better more open ended question would be, what router will give the fastest throughput with a VPN connected? Any idea?

Thanks!

Atheros based routers like the R7800 are the fastest. I do not have any real life figures though

well, R7800 has dual core 1,7 Ghz CPU and so far is next to last to R9000 witch is the most powerful router so far...
with VPN it will go 300+ MBs but it depends from type of encryption and VPN location i guess...VPN is very CPU intensive especially with high level of encryption....

300+ I can live with, just not as low as 60!

r9000 is 1.7 cpu, same as r7800. What about it would make it faster than the r7800 in regards to having VPN connected?

The R9000 has a quadcore Annapurna Labs AL514 processor (quad core Arm cortex A15) with hardware encryption accelerator, at 1.7 Ghz

R7800 has a quad core Qualcomm IPQ8065 with two 800 MHZ cores and two Krait 300 cores at 1.7 GHz basically a big.little chip. Krait cores are cortex A9 derived but performance wise almost A15 class.
This chip also has a hardware Crypto accelerator (AES/3DES/SHA).
