Hi there
I have a PIX firewall on my outside interface of the ISA firewall, and am
trying to enable the PIX to TFTP "in" to a server inside my network, and
fetch firmware updates etc.
As I have it, TFTP works on TCP69, but I can't quite get this problem
solved. Not quite sure if secondary connections are required etc.
What I have done so far is to publish the TFTP server on my ISA Firewall,
using a TFTP protocol definition that looks like this:
Port: 69
Protocol: UDP
Direction: ReceiveSend
What I can see is that when I enable the "Log Allow packets" on my Packet
Filter service, I can then see the inbound request to my ISA Firewall, thus
implying the request from the PIX firewall is definitely getting to my ISA.
Here is the excerpt from my Packet Filter log:
12/20/2005, 16:28:06, <PIX IP>, <ISA External IP>, Udp, 12345, 69, -,
ALLOWED, <ISA External IP>, -, -
Can someone please offer some advice on how to resolve this?
Thanks
William R.
