Static/Advanced Routing

I could do a simple thing and get a switch, but there are circumstances that
make static routing more ideal - if what I am looking to do can be done.
What that is is file and print sharing between computers that are associated
with two routers - a primary router/gateway and a secondary router that is
behind the primary router.

Behind my modem is a router. Behind the router are two wireless computers,
two wire-connected computers, and a VOIP phone. Behind that phone is another
wire-connected computer. The problem is that this phone acts as a router and
so the computer behind it is associated with a different subnet then the
computers on the primary router. Is there a way to change this cinsequence
through changing settings on the routers so that all computers are able to
associate at the level of the primary router? How?

I saw that there was a function on the phone to disable its DHCP Server
capabilities and a way to apply Static Routing settings with a Destination
IP, Subnet Mask, Gateway IP, Metric, and Interface. Is this where the action
takes place? Would I set the computer that is behind this phone to use DMZ?

Here is some IP info for the main router...
WAN IP Address: Will keep private
LAN IP Address: 192.168.1.1
Subnet Mask: 255.255.255.0
Domain Name: Castillo
Host Name: Castillo
LAN MTU: Auto
Local DHCP Server: Enabled
Default Gateway: Will keep private
DNS Server(s): Will keep private

And for the phone:
WAN IP: 192.168.1.250 (Static)
LAN IP: 192.168.15.1
Subnet Mask: 255.255.255.0
WAN MTU: 1500
LAN MTU: N/A
Local DHCP Server: Enabled
Default Gateway: 192.168.1.1
DNS Server(s): 192.168.1.1; Will keep private
Other Notes: WAN-level DMZ enabled for phone

You don't need to add a switch, you already have everything you need. You
don't want to use two routers. On one of the routers, simply turn off DHCP
which in effect turns it into a switch or (if wireless) an access point.
No, you don't want to ever put a computer in the DMZ. The DMZ means
"Demilitarized Zone" and a computer in the DMZ is placed outside of the
router's protection. It is sometimes used for hosting multiplayer games
over the Internet.

The main point is that you only want one router on your network. You can
have multiple switches and access points. In your case I would disable the
DHCP function on your phone and assign the wired computer a static IP on
your main subnet. Don't forget to manually assign DNS, too. Example when
using a Linksys wireless router:

IP address: 192.168.1.130
Gateway: 192.168.1.1 (the router)
DNS: 192.168.1.1 (the router)

Now whether this will work with your particular phone and its odd
192.168.15.x subnet I don't know. You might want to check with the VOIP
tech support people.

I manually configuered my internet connections on the computer that is behind
the phone to do the following...

IP Address: 192.168.1.103
Subnet Mask: 255.255.255.0
Default Gateway: 192.168.1.1
Preferred DNS Server: 192.168.1.1
Secondary DNS Server: Blank

Also, DHCP on the phone has been disabled.

The problem persists - I am not able to access internet through the computer
that is behind the phone. Do I need to do something with the Advanced DNS
suffix properties (apending)? Or enter a DNS suffix to use for this
connection? Does anything need to be done on the primary router?

Thanks,

You need to contact the VOIP/phone people's tech support to see what the
issue is. Whenever you add a non-standard item/setup into the mix you need
to see what the requirements for that non-standard item are. I'm sure they
know exactly how to set up a computer so it connects to the Internet using
their equipment.

That's not correct. It also has to be connected up differently because
it's still natting at the external interface.

What was formerly coming out of the WAN port on this router needs to
be plugged into a LAN port instead.

And you need to give the phone router a similar LAN address as this
computer so it is also on the 192.168.1.0 subnet


Jim.

A lot depends what kind of VOIP phone this is. Skype phones wil work through
a NAT router without alterations. The modern SIP protocol will require a
port-mapping through any NAT router or routers in the circuit, but should not
be difficult to setup. Older phones that use the Netmeeting protocol are far
more problematic, in fact these types are unlikely to work unless the phone
is directly connected, or in the DMZ.
