Got one or two customers who may move to UFB. Router installed is a Cisco UC320, which runs their phone system.
The UC320 cannot dot VLAN tag on WAN side; so will only work for non-tagged PPPoE connection.
Question: is there some type of router I can put between the ONT and the UC320 to take care of the VLAN 10 tag, but still allow the UC320 to do the PPPoE auth? This would need to work transparently so as to avoid double NAT etc.
A short how too guide would be great too.
