I have this exact same issue, I ended up adding in SysSockSetDefaultGateway("eth0",Gateway) after the UpdateConfiguredIPSettings to get around it

Cannot change default gateway from code

2021-09-01T13:50:28.428000Z

Hello!

I am experiencing some problems when trying to change IP-address, subnet mask and default gateway using Codesys standard method "UpdateConfiguredIpSettings". The IP and netmask is updated when the code is executed, but the gateway cannot be changed. I have attached a picture of the running code. And a gif showing displaying the problem.

Any ideas on what I can try? Am I missing a configuration parameter in the .cfg file or is there any other Linux background setting I need to change?

I am using codesys 3.16.3 together with the 4.0.0.0 runtime on a raspberry Pi CM3 based PLC. Network config is done in /etc/network/interfaces.d/*.
The options "Adjust operating system settings" is checked under the Ethernet device.
I have the following configuration in the CODESYSControl_User.cfg file:
[SysCom]
Linux.Devicefile=/dev/ttyUSB

[CmpBlkDrvCom]
;Com.0.Name=MyCom
;Com.0.Baudrate=115200
;Com.0.Port=3
;Com.0.EnableAutoAddressing=1

[SysProcess]
Command=AllowAll

[CmpApp]
Bootproject.RetainMismatch.Init=1
Application.1=Application

[CmpRasPi]
Architecture=armv7l

[SysSocket]
Adapter.0.Name="br_extmodbus"
Adapter.0.EnableSetIpAndMask=1

[CmpSocketCanDrv]
ScriptPath=/opt/codesys/scripts/
ScriptName=rts_set_baud.sh

BR,
Simon
