PIX is using PPPoE to get IP from ISP but the AC does not respond fast enough. We have detected with other systems (lynksys router 54NG and PC connecting using PPPoE) that the AC responds after receiving several retries (at least 10 every 3 or 5 seconds). the PIX retry timer of 30 s is not enough to establish the connection, is it possible to reduce the retry timer from 30 s to 5 s?
