I am having issues with a PIX 515E and Cisco 827 Router, I have tried to change the router to a better spec model 8274v, i copy the same config from the old 827, and connect to the adsl line, i get connection to internet fine but the corporate lan cannot get internet and neither can the pix ping internet, but pix can ping the router interface.
I tried using "clear arp" and "Clear xlate" but still no connection.
I reconnect the old modem and it works again.
what am i missing??
