HP2650 VLAN routing

[Harold Parker]

I am wondering if someone can help. I think this should be an easy fix but I am just overlooking something simple.

I have a couple of VLANS and I want to route between them. My ISP router is 192.168.1.1

From the switch CLI I can ping everywhere. From the 192.168.100.0/24 network I can only ping the VLAN100 IP 192.168.100.1 and the Default Vlan IP 192.168.1.104. From the Default VLAN I can ping nodes on the 192.168.100.1/24 network.

What do I need to do to get the node on the 192.168.100.0/24 to talk to the other VLAN and get out to the internet?

Hi,
the Clients in the 192.168.100.0/24 subnet needs the 192.168.100.1 to be their gateway and clients in 192.168.1.0/24 the 192.168.1.104.
then you need a static route at the device with the ip 192.168.1.1. Something like this
ip route 192.168.100.0/24 192.168.1.104
hope this helps

hostname "ProCurve Switch 2650"
ip default-gateway 192.168.1.1****!!!!!no need!!!
ip routing
snmp-server community "public" Unrestricted

untagged 1-16,21-50
ip address 192.168.1.104 255.255.255.0

exit
ip route 0.0.0.0 0.0.0.0 192.168.1.1



your switch conf true but no need ip default gateway

you make must be write static route on internet router
and check pc ip config
**************************
internet router config
****************************************************

192.168.100.0 255.255.255.0 192.168.1.104
and this router connect vlan 1 untag port
(internet router lan ip address must be 192.168.1.1)

*****************************************************

*************************
pc config
*****************************************************
vlan 1 member pc
for example
ip address :192.168.1.10
subnet mask:255.255.255.0
default gateway:192.168.1.104
and connect vlan 1 untag port

vlan 100 member pc
for example
ip address:192.168.100.10
subnet mask:255.255.255.0
default gateway:192.168.100.1
and connect vlan 100 untag port

finally

you can write ip route command on internet router

[ip route 192.168.100.0 255.255.255.0 192.168.1.104]

and check pc ip config

Thanks for your help. I have made progress but I have another problem.

I removed the "ip default-gateway 192.168.1.1" as suggested and I was missing the route to the 192.168.100.0/24 on my ISP router. Now I can ping back and forth between nodes on both sub nets. I am seeing one other issue - DNS does not seem to work for the client on VLAN100. When I try to do an nslookup I get

DNS request timed out.
timeout was 2 seconds.
*** Can't find server name for address 68.87.71.226: Timed out
DNS request timed out.
timeout was 2 seconds.
*** Can't find server name for address 68.87.73.242: Timed out
*** Default servers are not available
Default Server: UnKnown
Address: 68.87.71.226


DNS server 68.87.71.226 & 68.87.73.242 are valid for my ISP and works for clients on the DEFAULT_VLAN

Seems like DNS request fails from VLAN100

Do I need to do something to have the switch forward DNS requests similar to DHCP helper?

[cenk sasmaztin]

please send me sh run print

[cenk sasmaztin]

unable switch dns request like ip helper very different aplication

if you can not reachable dns server
you have routing problem on switch or internet router

please send me sh run print switch
