Pix 520 Firewall IOS upgraded

Would you recommend upgrading a 520 IOS across a frame relay link ???

We have a remote office that cannot access a specific web site our engineers have said I need to upgrade the IOS because we have hit a bug.

I don't have a spare to send them and I thought I could make my 3640 hold the IOS in a flash card and download it across the wan like I do my routers.

Re: Pix 520 Firewall IOS upgraded

It is really best, and with less risk, if you do the upgrade from a local tftp server.

You can get the 3com/Cisco tftp server (you can search google for download sites) and put it on a local laptop then upload the pix code to that pc before doing upgrade to the pix from that pc.

Regards,
