RouterBoard with 2.9.21 - Proxy Arp

When I try to change the ARP of an Interface to Proxy-Arp to bind a PPTP Service to that Interface I am getting an Error saying “Invalid MAC Address”.

Any idea why?

already discussed in other topics, please wait for fix later today

This problem is almost everywhere in 2.9.21 it will be repaired in 2.9.22 … see other topics for details. Downgrade eg. to 2.9.18 works well for me :slight_smile:

Normis was faster :slight_smile:

Thanks guys. I am going to istall 2.9.22 to check fix.
