route from 1 vlan to another
I have a network with 192.168.1.0(VLAN1) and 172.16.1.0(VLAN10).
The 172 is a VOIP system and the 192 is client computers. There is a small issue with routing from 192 to 172. There is a web interface on the VOIP phones that allows them to be configured.
I can ping from 172 to 192, but not back the other way.
There is a CISCO router and a switch. The router has gateway for 192 (say 192.168.1.99) and 172(say 172.16.1.99). A ping from 172 to 192 is successful. Traceroute shows it going from the 172.16.1.99 gateway to the 192.168.1.200 destination IP.
A ping from 188.8.131.52 to 172.16.1.200 fails except for 2 IP's the gateway and the dhcp are successful. The failure stops at the 192 gateway.
Why would some work and others not?
