I am running an CPE (customer premises equipment) application software in my Linux system and trying to connect to an ACS (both from Gatespace.com).My CPE s/w that tries to connect to ACS reports like this:
./cwmpc -d -v -D 0x3 -w eth0 -l eth0

When I contacted Gatespace.com, I was told that it was some kind of iptables problem. Can I get some help to fix this problem? Through browser, I could connect to the site I was asked to do, but the CPE software doesn't.

First, what version and distro of Linux are you using? Also, this seems like a problem with the software from Gatespace. It seems like somewhere in their software, you have to tell it which network interface to use for a default route to the rest of the world, and it's not getting it.

Also, the messages seem like it's using the route commands from Linux, but they're failing since they're already there. Make sure there isn't another copy of the software running ("ps -ef | grep cwm"), and kill it if there is, then try to restart. You could also reboot the box, if that's easier for you, and see what happens.
