There is no real way to avoid talking to your network administrator about this. If I understand your desciption of the setup correctly ... and this is a real source of uncertainty, as I've assumed a lot in filling in gaps in what you actually said ... whoever is in charge of your network *intends* to interfere with your ability to use ssh (for example) to access the Internet. Working around designed-in limitations to your Internet access isn't really a Linux problem, although if you find a type of workaround that will server your needs, then finding a Linux application to do that workaround surely is. But the first thing you need to do is get a better understanding of why your access comes with these limitations and whether your network administrator is helpful with or opposed to your efforts to work around them. - To unsubscribe from this list: send the line "unsubscribe linux-newbie" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.linux-learn.org/faqs
