My Core One is connected (bridged) to a Huawei Fiber system. The default config in the ISP supplied ONT uses VLAN’s and DHCP. My replacement ONT’s (Ubiquiti) will happily connect this way too, configured as the end router device with a VLAN.
But the Peplink refuses to connect up in bridge mode using a VLAN value. It connects OK without VLAN value, but not with a VLAN set.
I have captured the WAN1 packets via the support page, and can see the DHCP Discover / Offer packets all there and going back and forth. But the Peplink refuses to accept to Offer (which is identical with or without VLAN setting). In VLAN mode the Peplink prefixes the 4 byte 802.1q vlan header to the request, but the dhcp offer packet has no vlan ID header. Is that the issue? Is the Peplink refusing to accept the DHCP offer because the vlan id is missing?
Thanks
