Trying to choose between
867VAE-K9 and 887va for VDSL2+ and a 2nd WAN (cable) for redundancy backup.
Do they support HTTP proxy (upstream proxy)?
Would they work as a pass-through modem?
Would they accept a line from a pass-through modem (2nd WAN)?
Would they balance 2 WANs or can do redundancy (one at a time - with auto fail-over) only?
What about the OS versions/upgrade releases for them?
Any QoS differences?
Maybe it is batter to go 2900 series with relevant interface cards?
Any help appreciated, thanks.
