pcanywhere not working with cable modem and two routers

I have a cable modem from CableVision.  I cannot log into it to change anything.
The LAN IP is 192.168.100.1
The WAN is dynamic.

I need to connect this with my Vonage Router (192.168.100.290 AND my internal router (192.168.100.28) or hub.

I have tried many different combinations, with the gateway at 192.168.100.1 & .29 & .28 -- depending on how I was wiring things.

PCAnywhere can connect if I go from cablemodem to one PC.
It does not work with any of the following:
cablemodem to vonage router (.29) to smc router with gateway at 192.168.100.29 (all outbound works)
cablemodem to smc router with gateway at .28
cablemodem to hub with gateway at .1 (if I use the dynamic WAN gateway it does work, but that is not acceptible).

Can anyone help?

Not sure what you mean by opening the ports.

If i run the network cable directly to my pc and use DHCP -- PCAnywhere does work.
I am assuming 2 things:
1 you want to use Vonage.
2 It does not work now even though your internet does.

If that is the case then you need to open ports on your cable modem / router.

Plug in Vonage to your cable modem.  Does your Vonage work?  If so then the ports are open on the cable modem.  If it does not work then your ports are closed on the device..

Think of it this way.  The router is a harbor where boats dock and import or export goods.  If a specific port is closed then nothing can come in or out of that port in the harbor.

THe same way with routers.  If port 80 is closed, you have no internet.  You can still email the outside world through MS Outlook but you cannot surf the internet.

The same way Vonage uses certain ports and they need to be opened so that Vonage can work effectively.

That being said, if the ports are closed either open them or have your ISP (internet service provider) open the ports for you.
Thanks JNL - to confirm....

internet to cablemodem (phone and internet) to vonage router (2nd phone line) to lan router or hub.

Vonage works and outbound internet traffic works.
All firewalls on Vonage device and lan router are OFF.
PCAnywhere from outside does not work.

OK great then you do know.

Next you need to open ports VONAGE uses.
http://www.vonage.com/help.php?article=89

After that test it out.

You see if you have the cable modem connected to your firewall/router and the LAN port of that connected to VONAGE that is the correct sequence.

Let me know if oyu get stuck.  If you need to troubleshoot it.  Remove the router/firewall and connect Vonage directly to the cablemodem.  If that does not work you have to call the ISP to unblock these ports.
Iif the Vonage phone is working, I have to assume the ports are open.

I am familiar with PCAnywhere port settings an use 5631/32  33/34 and 35/36 on different PCs.

If I reroute my connection to:
internet -> cablemodem -> smc router (gateway 192.168.100.28) WAN port -- I get internet access.
However, whether I run a cable from the SMC LAN to the Vonage WAN or LAN I do not get the Vonage telephone.

I may need to contact SMC to see where to open Vonage ports, if necessary.  With other routers, they were automatically open.
I did spend time on the phone with Vonage and SMC.  But none of this helped.

I am going back to my Verizon router and Verizon VOIP...because that does work.

Thanks, all
You said:
"internet -> cablemodem -> smc router (gateway 192.168.100.28) WAN port -- I get internet access.
However, whether I run a cable from the SMC LAN to the Vonage WAN or LAN I do not get the Vonage telephone."

If Vonage works before the SMC router but not after then why dont you have it go:
INTERNET->CABLEMODEM->VONAGE->SMCRouter (see if this works)
alternate solution:
INTERNET->CABLEMODEM->SMCROUTER(wan=cablemodemLAN/lan=192.168.100.1)->VONAGE(wan+192.168.100.1/lan=192.168.1.1) AND hook up your PC to the SMC and not the Vonage ip scheme.

This way you are creating a V-LAN (virtual lan).  This means that you are segregating the two different types of traffic on your network data/voice.  On a corperate network companies do this as part of queuing and security.  As I see it this may help because this way your devices and yourself will not get confused by different gateways.

All devices pluged in to the lan side of the SMC will have a gateway of 192.168.100.1
All devices pluged in to the lan side of the VONAGE will have a gateway of 192.168.1.1
All devices pluged in to the Cablemodem will have a gateway of Whatever the modem LAN ip is.
