I am installing virtual machines at our location and have 2 stacked HP 2920 switches. I have all the network communicating, but I can't get the virtual servers to the Internet. Using ping and pathping, I think the problem lies in the switch configuration (attached). The firewall is 10.10.0.3.
Solved! Go to Solution.

Hi,
I think you missed the attachment. Please check if your gateway is the VLAN IP Address of the switch and it has route to your firewall.

Re: HP 2920 switch won't allow acess of servers to Internet
Sorry if I seem like a newbee on this one, but the VLANs have their on gateway internal to the switch. The switches IP is 10.10.0.1 and has a gateway which is the IP of the network firewall. The only thing I noticed was that the running config listed a "Primary" as VLAN 10, when the default VLAN is the IP address of the switch. Is there a way (and should I) of changing this "Primary" to the default VLAN?

Re: HP 2920 switch won't allow acess of servers to Internet
Your switch looks fine.
Does your firewall have a route for 10.10.50.0/24?

Re: HP 2920 switch won't allow acess of servers to Internet
In the beginning, I went through a lot of headaches with the firewall. It is a Cisco ASA 5505 firewall. I have attached the running config for the firewall.

Re: HP 2920 switch won't allow acess of servers to Internet
Vinces guess was on target, the ASA lacks proper route to inside networks:
Current config has:
route inside 10.0.0.0 255.0.0.0 ASA
This route should point to L3 switch instead :
route inside 10.0.0.0 255.0.0.0 10.10.0.1

Re: HP 2920 switch won't allow acess of servers to Internet
Thanks. I do have a question though (trying not to sound like a newbee), If I enter the command "route inside 10.0.0.0 255.255.0.0 10.10.0.1, will that change the current route or add another one?

This entry will add additional route on your ASA FW, even if next-hop is the same.

OK, I entered the command but still cannot access the Internet for updates with the virtual machines.
