No default route after reboot using Gateway Groups.

@amorphous
and most importantly , before you make changes to the file, make a copy of it . Otherwise , in case of an error, the system will not boot and will have to fix the error for a long time

@amorphous
if you make wan_dhcp2-tier1 and wan_dhcp-tier2
the log will already look like this

@konstanti No luck unfortunately. Still doesn't work. I need to Disable -> Enable the WAN.

This is my configuration:

@amorphous
Hey
Having carefully studied this log, the only explanation of what is happening is that the boot process is happening with a slow read/write device (usb key) . Thus, the script to get the ip address does not have time to create the em0_router file in the /tmp directory. Because of this, there are problems with the initialization of the routing table .

At the moment, I propose such a solution

Prevent deleting temporary files on reboot .

Another option is to make additional changes to gwlb.inc (but this need to test and inspect )

[Rico]

Are we still talking about the topic here which is No default route after reboot using Gateway Groups?

-Rico

[Konstanti]

@rico

I'm sorry this is being discussed here.
Just in the case of amorphous necessary
1 make changes to the gwlb file.inc ( solved)
2 solve the problem of slow usb key

[amorphous]

@konstanti Yeah, we should switch to :

Thanks for all your help so far.

[0daymaster]

@Rico Is this fix for IPv4 only? Or should this also work for a default IPv6 gateway group. Thanks.

[Rico]

I have not checked with IPv6, you need to try.

-Rico

[0daymaster]

@rico This fix works for both IPv4 and IPv6. Thanks.
