WebGUI not accessible via SelfIP, caused by RST from internal host

[Mahi]

Hello,

I have a BigIP device with only one self-IP with port lockdown to allow 'all' ports, however, the WebGUI is not accessible over the self-IP. I can see the below log message in /var/log/ltm folder though'

"RST from BIG-IP internal Linux host"

Please let me know if there is a way to resolve this. Thanks.

Hi Mahi,

You can identify the reason of the TCP RST with this command below :

tmsh show net rst-cause
 
(To reset rst-cause stats) :
reset-stats /net rst-cause

Yes Lidev, I got the above output from the logs after enabling the TSP Reset Cause. I see the same cause when I did a packet capture on Wireshark on client computer.

Did you test the WebGUI connection on the Self IP with a CURL ? What is the outcome (HTTP/1.1 200 OK ?) ?
