I typically default to Trunk mode, and then use General mode if there appears to be some interoperability issues. Do you have a couple of workstations/laptops you could plug into access mode ports and ping between? For external communication, I would double check and ensure that the firewall has routes back to the internal VLAN subnets. If it does not, then this means that traffic will not be able to return. Performing a packet capture could help shed a lot of light on. Start at the port that the server plugs into, observe the tagged packets coming into the switch, and then follow the packet throughout the network. Then once the packets changes to something unexpected, or is dropped, you then have a better idea of the area to troubleshoot.
I'm new to configuring Dell switches and I'm having an issue with routed VLANs. There are several VLANs on this switch, but I'll isolate the problem to 2 of them for simplicty. VLAN 300 - 10.10.0.0/25 VLAN 301 - 10.10.0.128/26 Both sharing a single interface going to an ESXi host. VM's on this host with the following network config: Host 1 10.10.0.45 255.255.255.128 10.10.0.1 - Gets through the firewall, can ping any other hosts on the 10.10.0.0/25 network, and can ping hosts on the 10.10.0.128/26 network Host 2 10.10.0.140 255.255.255.192 10.10.0.130 - Can ping any other hosts on the 10.10.0.128/26 network, but cannot reach the 10.10.0.0/25 or external network (which is using 10.10.0.1 as the default gateway). !Current Configuration:!System Description "Dell Networking N3024, 6.2.6.6, Linux 3.6.5-50bbccb7"!System Software Version 6.2.6.6!configurevlan 300-307,310-311exitvlan 300name "Site Management"vlan association subnet 10.10.0.0 255.255.255.128exitvlan 301name "Application Management"vlan association subnet 10.10.0.128 255.255.255.192exitvlan 302name "CFS Fabric"vlan association subnet 10.10.0.192 255.255.255.224exitvlan 303name "Application Fabric"vlan association subnet 10.10.0.224 255.255.255.224exitvlan 304name "UMG Fabric"exitvlan 305name "SBC Core Fabric"exitvlan 306name "Trusted HA"exitvlan 307name "Untrusted HA"exitvlan 310name "Firewall Access"exitvlan 311name "SBC General Access"exitslot 1/0 1 !

My gut is telling me there must be some issue with the gateway settings on these higher VLANs because they can be pinged, but cannot ping. I currently have the gateway address on my hosts on the 10.10.0.128 network set to 10.10.0.130, which is the IP address I have given to the VLAN interface for that VLAN.
