I need to set up a GRE tunnel through the PIX. It should be pretty easy, but I am having problems. Does anybody have documentation they can post?? Thanks in advance.
Remember that GRE is a protocol (number 47), not a port, so your access-list must reflect that (eg access-list 101 permit gre ....).
If it doesn't help, can you post your relevant pix config, and explain what is happening. Do a show log, and look for denies. Show xlate and show conn are also useful for troubleshooting.
Hope it helps.
