xr500 ip fragmentation ps4
Hello i have an ip fragmentation Problem with the new Duma Os.
I use the xr 500 and already test my MTU. MTU max is 1472 but i still get the IP fragmentation message when the PS4 hits the NAT test ...
It’s wired
Fritzbox 6490 cable with the last available Firmware from Fritz
I also have the last available firmware on the xr router. 2.3.2.32

You ISP modem already has a router built in:

Modem Combo Units:
Couple of options,
1. Configure the modem for transparent bridge mode. Then use the NG router in router mode. You'll need to contact the ISP for help and information in regards to the modem being bridged correctly.
2. If you can't bridge the modem, disable ALL wifi radios on the modem, configure the modems DMZ for the IP address the NG router gets from the modem.
- Yes it has a router buildin but I made everything with the isp support and it’s already in bridgemode in lan port 2.
I also dmz the up from the xr. And turn all wifi off.- Where have you set MTU? Just on the PS4 itself? You should also mirror this on the router so they're the same. If you reset the MTU does it work correctly? If so then you either haven't worked it out correctly or you're not inputting it in all the places needed.
- I set it in the dumaos and in the Ps4.
When I set it in the router and test the internet I have no fragmentation warnings. But for the Ps4 I have the message all the time doesn’t matter which MTU I set. Even when I put in the lowest possible.
My isp is good for 1472.
By the way Thanks for the answers
