Good evening friends

I'm working on a project in which i had to set a logo network, i use one of the LOGO devices for receiving variables from the other ones in the network, and then i set a webserver in that LOGO in order to watch the whole project variables.

The project was working allright when i first tested in my office, but when i installed it on my client's building, there where somo aplications that didn't work allright, i guess it could be something related to the communication ports that uses the LOGO, and the network firewall of my client.

Does anyone can help and indicate me which network ports does LOGO uses in order to create exceptions on my clients firework?

Regards,
