routin with win2003

[ammadeyy]

2626 switch the followin config

vlan 1
name "DEFAULT_VLAN"
untagged 1-26
ip address dhcp-bootp
exit
vlan 2
name "ADMIN"
ip address 10.17.6.1 255.255.255.0
exit
vlan 3
name "POS"
ip address 10.17.4.1 255.255.255.0
ip address 10.17.5.1 255.255.255.0
exit

i am using windows 2003 as a router for the time, ip is 10.17.1.13

clients gateway will be 10.17.1.13

10.17.4.1 cannot talk with 10.17.5.1
10.17.6.1 cannot talk with 10.17.4.1

anyone can tell how can i do that?

if i read this correctly, you've got 3 VLANs, all attached to all 26 ports, with a Windows box as your router.

clients on 10.17.1.0/24 can get to any other subnets, but clients on the other 2 cannot get anywhere.

if this is correct, the cause is the fact that your default router is not on the same IP subnet. you have to do the binary math, but in short, the default gateway is the host to forward packets to in the event no other rules match. it must be on the same subnet as the client, so the client can talk to it without consulting the routing table.

easiest fix, add ip aliases for 10.17.4.13, 10.17.5.13, and 10.17.6.13 to the network card on the 2003 server.
