CBR750 not working with BIG-IP VPN software

[SanDiegoCBR750]

I have a new Orbi CBR750 (AX4200) with one satellite.  The connectivity is excellent from both the main router and the satellite.  Unfortunately when I connect to my work VPN (BIG-IP Edge Client) the connectivity degrades, first to intermittant problems, and then eventually it drops the inbound connection completely.  I did work with Netgear support over the chat app.  They had me modify the MTU size from 1500 to 1492.  After a few minutes the same problems reappeared.

Here is some additional data

CBR750 router firmware version: v4.6.5.8

Orbi satellite firmware version: v4.6.5.14

Armor disabled

I have worked with this VPN software for long time at home and while travelling internationally without this problem, so the it would seem to be coming from the Orbi CBR750.

Are you using a wired or wireless connection to the CBR? 

What Firmware version is currently loaded?

Does a different brand of VPN experience the same thing to compare?

@FURRYe38

Thank you for your help.  Here are the answers to your questions:

1. I am connecting to the Orbi RBR and RBS over WiFi (not using a wired connection)

2. Firmware relieases:

CBR750 router firmware version: v4.6.5.8

Orbi satellite firmware version: v4.6.5.14

3. My wife is experiencing the same connectivity problems when she connects over her company's VPN.  She is travelling so I do not have her VPN software name.

Again, thanks

I wonder if you use the CBRs DMZ for your PC, if this changes the behavior. 

No running out of ideas. Possible FW is not handling the VPN correctly or maybe some compatibility issue. 

I would make contact with NG support and let them know what your seeing.
