Routing email and snmp through 2 NICs in server - how?

Hi All

The scenario: I have my SAN box in an isolated VLAN-X , I am only able to connect to the SAN Management console by using a Second NIC in one of my virtual servers as I don't have any available ports on my switch stack. The NIC 1 is on the main VLAN-Y.
Not a nice solution but it is all I have.

Can anyone give me a clue how to route only email (SMTP) and SNMP from VLAN-X to VLAN-Y via the server for alerting purposes. Or if you can suggest another way I would appreciate it.

Thanks

Eric

Do you have firewalls that handle VLAN-x, you would need to add rules to the firewall to allow traffic between vlanx into vlany when the destination port is UDP 162 (snmp trap) or 25 (SMTP), You could further restrict the rights be explicitly defining which systems vlanx can access on these two ports in vlany.

Depending on your SAN you might be able to define the IP that the SMTP notification uses and which IP the SNMP trap is using.

Hi Arnold

Thanks for responding, the only place the 2 VLANs have a connection is via the Server that has 2 NICs. NIC1 is on subnet 35 - VLAN-x and NIC2 is on subnet 110 - VLAN-y

I have defined the SAN SMTP to go to the SMTP server on the 35 subnet but how do I ensure is goes from 110 to 35 to be delivered? I have added a route from 110.0/24 to .35.13 on the storage switch but how do I get the server to route? or am I missing something else?

Thanks

Thanks for you help, I enable routing on the server and added the static route on the SAN side switch and a static route on the production network side switch and voila it pings and I can get my alert emails.
