I am going thru some online configs for ASA/PIX and noticed in the below link the MTU change when PIX/ASA gets public IP via PPOE.
I have a site setup with PIX receives IP address via PPOE and also has VPN tunnel (as backup to primary T1) to one of our data centers. It is observed that, when T1 has issue and VPN comes up, the DSL drops the internet connection occassionally (and so the VPN tunnel). Was this to do anything with MTU setting..? Or anything esle might be causing this.
Thank you in advance
