Linux Firewalls and Cell Phones


Hello all,

I have what has proved to be a tough problem for my Linux skills. I recently had to reprogram our Linux firewall at my office after the old firewall.conf file fell off the face of the planet.

We have a service call dispatching system that allows our techs to check and close their calls via their mobile web browser.

After installing the firewall, They cant reach the system on their phones. Our branch offices can reach the network using their static IPs.

My question is how can I give them access to this IP when we don't have a static IP to work with. I am willing to open this one IP to the world as its not really a threat.

I have tried to get the IP range from the cell phone carrier, However they "don't disclose that info"

We are using RC firewall under Gentoo Linux.

Thank you for any help you can provide!!!

- Ryan

Sorry I'm a little lost here. How can yu run a HTTP service on a dynamic IP? Does the server running the application have a static IP? If they are using a browser, then they must be typing in a URL. If they are just allow that port through to all.

Do you keep advising your customers whenever the Server IP has changed??

i think he means the cell phones are all using dynamic ip's

RJNeely- can't you just add some password authentication to you web app/site and open the port on the server rather than open the server to the world

thatt way your mobile dynamic users will be able to connect and you dont have the whole box exposed
