Hi,
      I’m missing a trick here. I need to get ftfp access to my perimeter 2811 router through my pix. I’ve already amended my outbound access-list to allow telnet access which works. I then added another entry fro tftp and no joy. I then added the same entry to my Inbound access-list and still nothing. Here are te pertanent bits of my list.

Outbound:

access-list Outbound extended permit tcp host 10.1.5.121 host 172.16.0.1 eq telnet
access-list Outbound extended permit tcp host 10.1.5.121 host 172.16.0.1 eq 69

Inbound:

access-list Inbound extended permit tcp host 172.16.0.1 host 10.1.5.121 eq 69

Any ideas? Thanks.

What are you trying to do?  Backup your router config?  Update the IOS?

Backup the config at this stage.

In that case, you would be initiating the TFTP from the router, correct?  Make sure you have a route statement in the router that lets it know to route traffic destined for your internal ranges back to the pix.  What do your route statements look like in the PIX and in the router?

What Is Threat Intelligence?

Threat intelligence is often discussed, but rarely understood. Starting with a precise definition, along with clear business goals, is essential.

My tftp client is on my desktop machine (10.1.5.121) and is initiated from there. I have routes to my perimimeter router and back all sown up, traffic passes properly. I'm sure this is a access-list problem. I can use my tftp client to pull the config from my pix no problem.

I'm sorry, but I've never initiated a TFTP session to ANY Cisco device from the client.  It's always been from the device.  Here's a link explaining the device initiated method.  Give it a shot and see if that works.
