Uc540 10.1.10.1 no interent

[gameover1320]

Hi,

i have a uc540vlan100 for voice(192.168.0.10, 10.1.10.1, 10.1.1.1) gateway 192.168.0.253 Windows 2008 server dhcp data 192.168.0.6

Expansion from uc540 plugged into expansion on sg200-26 switch. Have sip in wan port of uc540. From uc540 i can ping outside from 192.168.0.10 network. I can ping internal network ie: gateway but not outside from 10.1.10.1. Without 10.1.10.1 having outside access cannot get voicemail to email notification to work.

when i can to setup nat in uc540 it wants to link to wan subnet. the wan connection is sip with no internet.

any help would be great

thanks

Hello Mike,

You should add a static route to the sip link and add default route on the UC to the Internet gateway.

HTH,

Alex

   the sip does not provide the system with internet. Added static route 10.1.10.1 255.255.255.255 and fast ethernet. still 10.1.10.1 has no outside access

Try adding the static route:

ip route 10.1.10.1 255.255.255.255 Vlan90

(with the Vlan90 int being 10.1.10.2)

This is what worked for us.

Do you have a 3rd party firewall in the mix?  A internet router/firewall needs to have routes back to the UC500 for the voice vlans. 

[gameover1320]

the only thing in the mix is a gateway rv042g with static route 10.0.0.0. the static route is to let data network access the CUE

[Brian Rapier]

Is there a route on the RV that points to the UC, so it knows where to send the 10. data?

On the RV

ip route 10.1.10.0 255.255.255.252 192.168.0.10 <-- Your UC data network interface IP

ip route 10.1.1.0 255.255.255.0 192.168.0.10

On the UC (these are my static routes)

ip route 0.0.0.0 0.0.0.0 192.168.0.2

ip route 10.1.10.1 255.255.255.255 Vlan90

ip route 10.1.100.1 255.255.255.255 Vlan100

ip route 192.168.0.0 255.255.255.0 Vlan1

If you have a 3rd party router... then you need NAT for those networks as well.  so check out the NAT settings on the RV and make sure the 10.1.10.X and 10.1.1.X networks NAT to the internet.

8rv042g has one to one nat. will not let me add the 10. networks to nat. only 192.168. on private for nat

[JOHN NIKOLATOS]

Well I think your issue is the NAT at this point.  I am reading on the forum about the RV042G may not support NAT in the way you need.  Can you just bypass the RV042 and plug internet in the uc500? 

[Brian Rapier]

Where is it located and what is the email server you are using? 

You should not need to NAT the 10.1 addresses to the outside, they are not connected to the outside, they are connected to the 192.168 subnet.

All it should need to know is the gateway to the internet 192.168.0.253, now the 192.168 subnet needs to know how to get to the 10.1. subnets, and that is through the 192.168.0.10 address.

Recheck your static routes and see if you can watch a log on the RV unit to see where things are going.

[JOHN NIKOLATOS]

Mike post your exact static IP routes from the RV so we can see them.  I want to see what you place in the static routers back to the UC.

[gameover1320]

rv static routes are: 10.1.10.0 255.255.255.252 192.168.0.10,   10.1.1.0 255.255.255.0 192.168.0.10

that is the only two static routes in the rv

the static routes in the uc540 are 0.0.0.0  0.0.0.0  192.168.0.253    10.1.10.1  255.255.255.255   integrated services    173.46.30.0  255.255.255.0  10.0.2.69 this is for sip
