RV345 and Comcast business routers same IP address

[miket64]

I have rv345 

My current network configuration is as follows.

The RV345 is dishing out 192. addresses for my wired network

My Comcast business wireless router is dishing out 10. addresses.

How do I get the wired and wireless to talk to each other, get the same ip address range so the wireless network can talk to the

resources on the wired network?

is this 10 address in the same Router ? or 2 different connection?

[miket64]

the 10. addresses all come from the comcast router

Hi

Can you provide some info/confirmation on below points?

1. Is the RV345 having its own separate internet connection? And if yes are the lan-hosts connected to the RV345 (and getting ipaddress of 192.168.x.x network by the dhcp-server on RV345) accessing the internet using the internet link on RV345?

2. Is the comcast wireless router having its own/separate internet link?

if yes, are the wireless-lan hosts in 10.x.x.x network (assigned by the AP/dhcp server on this comcast router) accessing the internet via this comcast router?

If yes to both points above, then one of the possible methods to integrate both these lan-networks (192.x & 10.x) would be as below:

Assumptions:

1. We can create vlans/tagged-vlans on the lan-ports of the comcast router

2. We can add static-routes on the comcast router

3. This assumption is that

a) the lan-network 10.x.x.x on the comcast router is  in the default vlan1 on comcast router

And

b) the lan-network 192.168.x.x on the RV345 router is also in the default VLAN-1 on rv345

Step-1: connect say lan-port-15(and not lan-16) using a patch-cable to one of the lan-ports on comcast-router

Step-2: On RV345, create a new vlan, say vlan1001 and assign it a ipaddress say for example 172.16.1.1/24 ( or whichever ip address that is free on the comcast router network)

- this will be a tagged-vlan on all lan-ports of RV345, including LAN-port15

- and next apply and also do a permanent save

Step-3: Next on RV345, in routing/static-route gui page, add a static route to destination 10.x.x.0/24 via gateway address 172.16.1.2 and interface would be vlan1001

Step-4: Next on Comcast router create a new vlan1001, and assign the ipaddress 172.16.1.2/24 to this vlan1001 interface on comcast-router

- this will be a tagged-vlan on all lan-ports of comcast, including the lan-port connected to RV355 (to lan15)

- apply and do a permanent save

Step-5: Next on comcast router, add a static route to the destination network 192.168.x.0/24 via 172.16.1.1 and interface would be vlan1001

- do a aply and save

Now both networks 192.x and 10.x should be able to communicate with each other

try it out
