When I migrated a config from a 750G to a 450G, I found that the names of the ethernet ports were applied to the wrong physical port. When I plugged a cable into physical port 1 on the 450G, the RouterOS showed a link on the interface named 4_tower_lan. 4_tower_lan was physical port 4 on the 750G. I had to figure out which port showed a link with a cable plugged in and rename the interfaces so that the configuration of IP address and DHCP clients would be on the correct physical ports. -- Scott Lambert KC5MLE Unix SysAdmin [email protected] -------------------------------------------------------------------------------- WISPA Wants You!
