    hello everybody

    I am configuring an Allied Telesis at-ar415s router. after the basic configuration with nat, access lists, default route etc it was ok, i mean i have access to internet and the internal e-mail was ok. i saved the configuration. after i rebooted the router i noticed that the configuration was saved intact like i did it, but i didnt have access to internet. after trying several times i noticed that if i deleted the the external interface configuration with public ip (the default route configuration was deleted too automatically), and then configured it again (and the default route too) it could work,i had access to the internet. i saved the config again, i restarted the router to test and no internet again. i deleted the external config again, configured it again and it was ok again with access to internet. if i reboot the router i get no access to internet again. and so on......

    the network config is like this:

    isp--modem---router---switch--users
    ....................................l
    ............................wireless router

    does anyone have any idea because it seems very weird to me?
    can anyone help me on this pls?
