I have configured a NetVanta 3305 with a WAN interface on Eth0 and a LAN interface on Eth1. The unit receives a WAN IP address from my ISP via DHCP and everything appears to be functioning there. I configured NAT on the router through the Firewall Setup Wizard and have a DHCP enabled as well. From the client end, the client is receiving an IP address from the 3305, however, the default gateway it's receiving via DHCP is not the default gateway of the router. For example, the client receives the IP address 192.168.0.100/24, with a default gateway of 192.168.1.1, when the IP address of the LAN port on the 3305 (Eth1) is set to 192.168.0.1. I would be happy to post my configuration if it helps any, but I was curious as to whether or not anybody has an idea of what might be going on.
When you get a chance, is it possible you could reply with the firmware version, and a copy of the current configuration (please, remember to remove any information that may be sensitive to the organization)? I will be happy to review it for you, but this may be something that we will need to run DHCP debugs or a packet capture to diagnose. However, hopefully, the configuration will point us in the right direction.
Please, do not hesitate to reply with any additional questions or information.
