Before I ask a specific question, I'd like to see if the community can point me to the appropriate documents to educate myself. My situation is pretty simple:
1. I have a NetVanta 3133 SDSL router connected to a single SDSL provider
2. I have a number of static IPs which are routed to that router
3. I also have a high-speed cable modem with no static IPs
4. I have two internal subnets, 10.x (personal) and 10.y (business)
5. I have a website and a mail server that live on 10.y and get routed through the SDSL router
6. I have another website that lives on 10.x that I'd like to route through the SDSL router (because of the static IPs)
The high-speed modem is my gateway for 10.x. My SDSL router is my gateway for 10.y. Until now I had a Netopia router and it was pretty easy to configure all of this. With the NetVanta it's a little more challenging, at least for me. I create two VLANs, one for 10.x and one for 10.y, and assigned each to a different switchport. I learned how to do port forwarding and I've managed to assign different external static IPs to different internal ports. I was able to get most of the individual pieces working at one time or another, including access to both the 10.x website and the 10.y website and mail server. Here are some of the issues I've run across:
1. I can't have both VLANs up unless I filter BPDU.
2. If I don't filter BPDU, as soon as I connect the second port, to my network, one goes to Blocking status and I'm done.
3. If I do filter BPDU, I get other inconsistent results which I haven't yet had the time to completely isolate.
4. I haven't figured out how to originate outbound traffic from within either the 10.x or 10.y subnets, even if I only have one VLAN active and connected (at the end of the day, I may not want to do 10.x, but I definitely need 10.y).
So. I thought getting two subnets would be easy, but I'm not succeeding just yet. Right now I've only got one subnet connected, and it's inbound only. Am I on the right path for what I'm trying to do? Are there manuals or tutorials I need to read that will help enlighten me? Am I missing a basic point of some kind here? It's especially frustrating because I had all of this working with the Netopia.
Anyway, I'm happy to do more reading on my own before I ask silly questions. But any suggestions or comments are welcomed. I'm going out of town so I won't be able to do anything this week except read (I'm afraid to do anything that might require a physical reset of the box or involve connecting or disconnecting switchports from the network), but I plan to get back at this full-time this weekend.
Thanks in advance for any support!
P.S. One other thing I found - if the 10.x VLAN is enabled, it tends to shut down other computers in that subnet; they get Windows IP address conflicts, even though there are none. I have to go in and disable that VLAN and reset the adapters on the affected PCs.
