MR5100 throttles download speed on ethernet upon using IP passthrough
Hello mates When I am activating IP Passthrough on my MR5100 for static WAN IP, and use the ethernet port, the download speed throttles to max 200 Mbps although my backbone is 5G and I have 700-8...
you are right đ , this is due to different design M5 vs M6.
Dear Barry56
Thanks for your kind reply, however your mentioned steps might help newbie users or basic home users who are dealing for first time with professional equipment like MR5100.
FYI, I did all my tests and I am now somehow sure that the throttling is caused by the firmware (NTGX55_12.04.18.00 and earlier) or limitation in netgear internal iptables firewall.
Also in below thread people complained the same:
I was going to do below on my router, but I am not sure if TTL is causing the throttling or not, as on router mode the hotspot is working without any issue even on ethernet, but immediately when moving to IP passthrough, limitation starts. And the back router is not edge router, I tested with several routers from Synology and Linksys.
echo "iptables -t mangle -I POSTROUTING -o rmnet_data+ -j TTL --ttl-set 64" > /etc/init.d/ttl.sh
echo "ip6tables -t mangle -I POSTROUTING -o rmnet_data+ -m hl ! --hl-eq 255 -j HL --hl-set 64" >> /etc/init.d/ttl.sh
chmod 755 /etc/init.d/ttl.sh
So please in case you know someone from support, kindly ping him to be in touch with me as my 90 days period expired and I can't open a case directly.
Thanks a lot
I tried a lot to contact your support, nobody even bothered himself to call back or answer my query.
May you please just confirm the problem and if Netgear will release a new firmware to solve this issue?
Thanks a lot
Reads like the similar posts from the year 2020 reporting the limited performance of the IP Passthrough mode, while the normal NAT mode does perform in the 700...800 Mb/s, the IP passthrough does never exceed about 200 Mb/s.
Let's see if we can bring mcuadrado and JohnPeng to this coffee round again.

Yeah I already sent email to John and he replied that he will look to the issue although the device is not in high priority list.
Its sad to see the issue as the device costs me a lot upon purchasing a year ago and never tested the IP Passthrough because I didn't have public IP.
As the issue seems resolved in MR6xxx series, hope there would be some small modifications in firmware to make a customization on MR5100.
Cheers
