Netgate 4200 - internet speed slower ca. 10Mb/s than ISP router

[stephenw10]

Mmm, you may need to set the parent NIC to 1508.

However I would want more data points. You could just be seeing some random link rate differences or line loading etc.

Hello,
I set all back to default (so no MTU set in the GUI).
Please find attached screen shots from interface status and shell output for ifconfig -a
Maybe this can help you a bit.

WAN is on igc3 with VLAN 7 for PPPoE
LAN is on igc2

I tried different values starting with 1500 and then with 1492.

Trying ?
What about : pppoe ping determine packet size MTU
The answer is is probably on the first link. Like this one Ping Test to determine Optimal MTU Size on Router.

What's with the VLAN 7 tagged interface in igc3?

[johndoe102]

@stephenw10
VLAN 7 is required by my local ISP provider for PPPoE connection (VDSL in Germany). So not only user/password.

Then the PPPoE should be on igc3.7 not igc3 directly.

@stephenw10

Hello,
PPPoE is on igc3.7.

I did that too ... determined based on those descriptions ... the results I tried were: 1500,1492,1472,1464.
No difference. The download behind the Netgate 4200 is about 10Mb/s slower than if use the default ISP modem/router combo.

@johndoe102
Try 1508 for vlan7 interface and 1500 for PPPoE
Also try deferred setting
