There are 2 "ranges" with adresses assigned by PPPOE:
1 ip address + a range of 4(/30)
Case is to assign 1 public ip(from /30) to a device on the LAN.
this is SRX210 with X44 software.
We've set up proxy arp on wan-interface to be able to use extra-range(/30) and created static one-to-one nat to the device. communication almost ok but I wonder if the NAT maybe causing some problems with video-communication to and from the device.
the device mentioned is a video-conferencing endpoint.
I've tried to search but there are not many topic on this matter,
