sbc dsl with static ip

I also use a RV042 and I do not have astatic or PPPOE.

I use "http://www.dyndns.com/" and I created a free dynamic DNS acco

ount. The RV042 supports DYNDNS so all you have to do is enter your account info in the router.  Then forward the ports from the router you want to use to a static ip for your security camera system and that it;

This is exactly how I am using it.

See page 2 under PPPoE.

This is assuming your speedsteam is currently set up as a bridge and the RV042 is doing your routing.

SBC has stopped using static IP addresses.  Instead, they use sticky IPs.  You can simply setup PPPoE on your router (just like with a dynamic account) and SBC assigns you your static IP address.  Basically they have a reservation for your IP address that only allows your PPPoE account to pull the the static address they assign to you.

I enable ddns on the router and setup the account with dyndns.org.  I am still not able to even get to the router from outside.  I need to be able to use the ddns name with port 100.

what are your settings?

If SBC gave you a static IP address, you should not need to setup DDNS.  DDNS is for dynamic IP addresses, hence the name DynamicDNS.  
For testing purposes, I would forget about DNS for a minute and try connecting with the IP address.  If you need to get through over a specific port, you would type in your IP address followed by :portnumber.  For example http://1.1.1.1:100 
After you get the bugs worked out just using the IP address, you can then setup DNS and connect using http://domainname:100

Yes I agree about the static ips.  However I cannot use the static ip addresses given due to the dsl modem.  I have tried the ip address and the ddns address neither are working.

can you post your DDNS settings from your RV042?

Ok, so I re-read your original post and think I understand a little better now.
It looks like SBC has given you a static IP address, but it is being assigned to your modem, not your router, correct?  
If that is the case, the modem needs to be put into bridge mode and then the router needs to be setup with PPPoE.  The static IP will then by handed to your router by SBC when it authenticates with SBC.
To setup your modem in bridged mode, use these instructions:

under Setup -> DDNS does the status say "DDNS is updated successfully" on wan 1?

See jimmyray7's link for the RV042 setup for PPPoE

SBC says that the dsl modem is set to bridge mode.  Due to the model of the modem speedstream 5100, I cannot change any settings on it.  The SBC tech walked me through what should have allowed me to the gui screen.  I have attached a screen shot of the router wan setup.

Is that a screenshot of the Linksys Router or the Speedstream modem?  If that is the router, that should be correct.
There should be a status page on the router.  Check that and verify that the router is receiving the static IP address that SBC assigned to you.
If that is correct, then you would need to check your firewall settings and verify you have the necessary port(s) opened to allow access to the security cameras.  Looks like you mentioned port 100.

That is a screenshot of the router, the second screen shot from the router is further down in the document.  I just added a screenshot ddns at the bottom of the document.

Ok.  So now you need to check the Firewall settings.  Can you attach that?

Here is the firewall screenshot.

Were you able to set up PPoE per the document I linked to?  That should get your router to grab the static IP.

Yes it is setup for ppoe but I still cannot get access from the public ip.

Thanks for all the help the final step was to do port forwarding.  I had setup services for the ports I needed and an access rule.  I just added it to the port forwarding and it is up.
