Hello,

This week, we have encountered a problem with the ISP Orange in Spain.The requirements of this ISP are: DHCP and tagging vlan 832 priority 0. The fiber connection to GPON.


We have a Zyxel USG60 firmware 4.35  (have been tested with firmware 4.33 as well) connected for this ISP for more than 1 year without any problem, with the WAN1 configuration in DHCP and tag VLAN832 priority 0.

This week just stopped working. WAN1 connection no more than receiving the IP address.  It has been default reset to the USG60 and the connection still does not work.

The following tests are done:

- The ISP router is configured and the connection is correct
- Zyxel VPN2S firewall is configured with DHCP and tagging 832 priority 0  and the connection is correct.
- Windows Computer is configured with DHCP and tagging 832 priority 0 and the connection is correct
- Mikrotik router is configured with DHCP and tagging 832 priority 0 and the connection is correct
- Zyxel VPN100 is configured with DHCP and tagging 832 priority 0 and the connection fails

We found the same problem between USG60 and VPN100. We don't understand what may be happening with the Zyxel USG60 and Zyxel VPN100, but it doesn't work.

Any advice would be much appreciated.

Thanks!

Regards,
