PLEASE HELP.. same config but not working! from PA 3050 to PA 3220

L4 Transporter

It's a global setting so any asymmetric traffic would be affected. 

L2 Linker

Ah okay, but this global setting shouldn't be included in the config file that i exported from the old PA3050 ? 



L4 Transporter

It’s probably included but I don’t know for sure.

@SamerKiwan ,

So the configuration on your 3050 and your PA-3220 is going to be different in a few ways. Things I would verify:

1) On the PA-3220 are you using interfaces 17 through 20, and if so have you actually verified the interface is set to the proper speed if you are using SFP instead of SFP+? 

2) Importing a configuration like that can cause some issues if things don't 100% import properly. I would pull the PA-3050 and the PA-3220 configurations and verify that they are actually similar by running a compare. 

3) What do you see on the logs when you are attempting to browse? Resets or age-out responses? 

L2 Linker

Okay, Thank you very much for your responses. I will check and update you.

1) i am using ports 1-12
2) I didnt compare through config audit i will do so
3)i see resets, but all actions are allowed..

@rmfalconer what is the setting exact name of the asymetric routing ? below is my session settings


Session setup
TCP - reject non-SYN first packet: False
Hardware session offloading: True
Hardware UDP session offloading: True
IPv6 firewalling: True
Strict TCP/IP checksum: True
Strict TCP RST sequence: True
Reject TCP small initial window: False
ICMP Unreachable Packet Rate: 200 pps

@BPry I checked configuration syntax its exactly the same.. :S any other suggestions ? 

L4 Transporter

The setting that shows that asymmetry is permitted is "TCP - reject non-SYN first packet: False"

Is this on both firewalls?


Are you absolutely sure that this is a setting you want enabled? It's definitely not best practice to enable. Do you know why you have flows bypassing the firewall?

L2 Linker

For sure no i don't keep such setting, but i did that for testing purpose it was "True" i put it "False" to check if issue will get resolved but it didn't. Is it possible that A10 device makes such issue? maybe its SFPs are not compatible with the new PA ethernet ports?
