Confusing VLAN question
I have a DHCP server (Windows Server 2003 Ent) that I want to set up a superscope on. I bind 10.10.2.20 and 10.30.10.2 to the NIC and set up the scopes. That's not the problem.
I have two VLANs 10.10.x.x and 10.30.x.x. Routing and forwarding seem to be working except in the following case. I have one computer (10.30.10.14) in the 10.30.x.x VLAN and many computers in the 10.10.x.x VLAN. From the 10.30.10.14 machine I can ping any device in the 10.10.x.x VLAN EXCEPT 10.10.2.20 (request timed out)... From 10.10.2.20 (DHCP server) I can ping anywhere in the 10.10.x.x VLAN and I can ping 10.30.10.1 (gateway and address of VLAN 10.30.x.x) but not 10.30.10.14 (again, request timed out). From any other machine in the 10.10.x.x VLAN I can ping 10.10.x.x (including 10.10.2.20) and I can also ping 10.30.x.x. What am I missing? Last edited by vanblah; 09-30-2004 at 07:40 AM.. |

I'm assuming your subnets and routes are completely set correctly? As well as gateways?
Also, are you using IAS under Win2k3? Might also look here.

Yes. Actually I have edited the initial post to read:
From 10.10.2.20 (DHCP server) I can ping anywhere in the 10.10.x.x VLAN and I can ping 10.30.10.1 (gateway and address of VLAN 10.30.x.x) but not 10.30.10.14 (again, request timed out). It's strange because I can ping EVERYTHING from anywhere EXCEPT between those two machines. |

If you have two subnets bound to the same NIC (10.10.2.20) and (10.30.10.2), why would you want to ping the second IP on the NIC (10.10) if they're both bound to the same NIC? If you are able to ping from 10.3.10.14 to any IP on the 10.10 VLAN, at least you know your routes are ok.
This might be easier by instant messenger instead of posting in the forums. Send me a private message through the forums and I will give you my IM names (aim, yahoo, msn).

Bendsley - I have PM'd you my info.
I'm running ISA (not IAS) on the 10.30.10.14 server. Although right now I have shut down all of the ISA services to troubleshoot this weird problem. We may set up RADIUS at a later time on this server. We do use RADIUS on a W2K box; but the two machines aren't aware of each other. Quote:

UPDATE:
During lunch I rebooted the DHCP server (it's also a domain controller so I wanted to wait for lunch) 10.10.2.20 ... I can now ping 10.10.2.20 from 10.30.10.14 ... I still can't ping 10.30.10.14 from 10.10.2.20. This may be a firewall issue (10.30.10.14 is running ISA 2004). I can't find any explicit rules that prevent pings from 10.10.x.x network though. |

When I setup and ISA 2004 server, I wasn't able to do a whole lot with it without highly configuring it. Then I realized how much Windows sucks and went with IPTables on a Debian machine.

LDAP really isn't that difficult at all and Linux can authenticate through LDAP very easily.
