DHCP server options length limitation


We are testing Teltonika routers for a possible large-scale implementation in which they must assign by DHCP, not only the usual parameters, but also the IP address and port of the Wi-Fi controller in which the access points must register, using the option 43. This implies that the field attached to the “DHCP-Options” field must accept up to a maximum of 68 characters. However, it only accepts 64 characters. Is there a possibility of extending the length of this field to up to 68 characters?
The “DHCP-Options” field is located under the LAN / DHCP server / ADVANCED SETTINGS menu.

Kind regards,


Please update the device to the latest firmware, as the limitation is no longer present from 07.05.

Best regards,
