ta, Im having a heck of a problem.
One zone out to an ftp server is working frie but from another zone the conputers can connect but they cant get file listings of xfer data ata ll. Routing is fine, obviously, the rules they are hitting is ok, NAT and Sec.
Both connections go through two VRs to get out to the ftp server. One zone hits two rules, the other only hits one.
Im running out of ideas of things to check.
Anyone else here have this problem in the past? What was the issue? Thanks.
Solved! Go to Solution.
set deviceconfig setting tcp asymmetric-path bypass bypass-exceed-oo-queue yes
Here are all the options under asymmetric-path:
admin@PA-200# set deviceconfig setting tcp asymmetric-path bypass
+ bypass-exceed-oo-queue whether to skip inspection of session if out-of-order packets limit is exceeded
+ check-timestamp-option whether to drop packets with invalid timestamp option
+ urgent-data clear urgent flag in TCP header
<Enter> Finish input
set deviceconfig setting tcp asymmetric-path bypass yes
This disables the sliding window and sequence number checking. Looks like you are doing asymetric routing and the firewall is dropping tcp out of sequence packets.
Hope that helps.
