Flex H, a rant

We're still running on USG series firewalls in multiple sites because FLEX H series is unstable and we didn't buy USG FLEX (non-H) series because they will eventually become EOL devices in the near future (IMHO) since ZyXEL will focus on the newest H line (that's what companies do).

I've been monitoring these forums for a while now and you guys have my deepest sympathies working with the H-series.

If I would guess, ZyXEL decided to implement a completely new OS (makes sense) but released it too early and made us all beta-testers. It reminds me of Microsoft, who let go all the testing team and outsourced it (from India) and tried to use AI-driven automated testing for Windows 10-11, thus making users betatesters and this also explains why Windows 10 needed a lot of fixing to become production-ready (Windows 11 is not yet there, but making progress).

So I guess something similar happened at ZyXEL - some old-but-knowledgeable employees got ditched, maybe uOS development got outsourced to a different company/country, perhaps the QA team got ditched and oursourced? I guess we will never find out, but I think a lot of people will either switch to another vendor or wait a couple of years to buy another ZyXEL firewall.

You are absolutely right ticsystems.

Sadly we have a 700H in production and with another 700H in standby mode to implement to HA when firmware developed. I've been in constant dialog with Zyxel support for almost a year now to solve various issues. Firmware v1.30 has some hughe in and outgoing internet delay issues. If R&D team doesn't solve this ASAP within the next few days, we will replace this product with an older model or another brand. We've had it!
