For those of you using Multitech Conduit mlinux as your gateway I’d be interested to hear if you’re having problems with DHCP.
- Router with DHCP server is disconnected or powered off
- Conduit powers up or reboots, fails to get a DHCP lease
- Router with DHCP server is reconnected or powered up (conduit’s eth0 link state changes)
- Conduit never asks for a DHCP lease again. Device is useless until reboot.
It seems link state changes on mlinux don’t cause a DHCP Discover or Request. The only way to make a reliable gateway configuration is to use static IP addresses (which have their own limitations). The outdoor IP67 conduit has an external PoE injector (48v) so cannot be remotely reset without additional equipment or a site visit. Bah.
Can anyone suggest a fix for this?
