I have a SonicWall TZ210 running SonicROM 5.0.2.11. There are two ISPs: ISP A gives a static address and is currently working fine. ISP B offers a cable modem and a DHCP address. The TZ210 connects successfully through ISP A with the static address, but I can't get the TZ210 to receive an address from ISP B.
I have ISB B connected to the X6 port. X6 is in the WAN Zone and set to DHCP but no other configurations have been set. The status for that port shows 100Mbps full-duplex so layer 1 looks solid. I've added X6 to the Load Balance group and removed it with no change.
What steps am I missing to get DHCP working on the X6 WAN Port?
