VLAN 1 (data) 192.168.1.0
VLAN 2 (voice) 192.168.2.0
Firewall/Gateway: 192.168.1.245 (watchguard firewall) plugged in to switch port 21
The phones can successfully retrieve an IP address on the 2.0 network from the second DHCP server via the ip helper-address.
For some reason the phones can't reach the public internet. I don't know what I am doing wrong.
Full config attached. Thoughts? Thanks!
Solved! Go to Solution.

Re: Voice VLAN question for 2610-24-PWR
and you must write static route command on your firewall (to switch )
ip route 192.168.0.0 255.255.0.0 192.168.1.253

Re: Voice VLAN question for 2610-24-PWR
Cent, I'm not great with firewalls and routing so please forgive my ignorance. Are you saying this route....
ip route 192.168.0.0 255.255.0.0 192.168.1.253
...needs to be on the firewall and NOT the switch? Could you explain?
Also, is port 21 (gateway) tagged appropriately? Thank you!!!

Solutionfristly
ip routing command on switch for routing between vlan's and routing between firewall to switch or switch to firewall
if you want ip helper command and internet connection vlan user be required ip routing command.
secondly
you must be use static routing switch to firewall and firewall to switch
you write already static route command on switch but you don't write static route command on your firewall
running for static routing two router learn destination network address for manually with static routing command
you have two router frist router your switch and second router your firewall
therefore you must be write ip routing command on firewall (to switch )

Re: Voice VLAN question for 2610-24-PWR
If I put a PC on the ..2.0 network with the following static IP config, I can ping an external IP such as 69.63.187.19 (facebook), but can't resolve it by name.
IP address = 192.168.2.x
Mask = 255.255.255.0
Gateway = 192.168.1.254
DNS Server = 192.168.2.245
The DNS/DHCP server has two NICs. One NIC services the 1.0 requests (port 19 on switch), and the other services the 2.0 net requests (port 22 on switch)
What am I doing wrong? Below is the switch config again:
------ %< ---------
hostname "2610-24-PWR"
interface 19
name "VM Network"
speed-duplex 100-full
exit
interface 21
name "Firewall-GW"
exit
interface 22
name "DHCP-Voice"
speed-duplex 100-full
exit
ip default-gateway 192.168.1.254
ip routing
snmp-server community "public" Unrestricted
vlan 1
name "Default_Data"
untagged 1-21,25-28
ip address 192.168.1.253 255.255.255.0
no untagged 22-24
exit
vlan 2
name "Voice"
untagged 22-24
ip address 192.168.2.253 255.255.255.0
ip helper-address 192.168.2.245
tagged 1-21

exit
ip route 0.0.0.0 0.0.0.0 192.168.1.254

Re: Voice VLAN question for 2610-24-PWR
for ex: the 1st vlan will be in the same subnet as the servers subnet and the other vlan will have an ip helper address under it pointing to the ip address of the server that is in the other vlan.
