Hello,
Setup: XG135W V18 build 354.
I noticed today that I cannot ping properly some hosts like 8.8.8.8, 8.8.4.4, and 1.1.1.1. I launch a CMD, I type "ping 8.8.8.8" the first answer is correct, and then the 3 next are timeout.
This ping is passing through my #1 firewall rule "LAN TO WAN GENERAL RULE" which allows my internal lan to reach internet. I don't know since when this problem is occuring but it's really weird because if I switch on the capture packet in the firewall, the ping is working well ???!!! what the f*ck ???
Here are some screenshots to explain that...
The ping fail after the 1st successful answer.
Then I switch on packet capture, and ping again while it's still ON, and BINGO, ping is working:
Then I switch off packet capture, and ping is not working again...
Another weird thing is that, I monitor my custommer's firewall and internet lines with ping and other services which is alowed on a rule which is on the top of my #1 rule. This rule allows to ping those specifics IP, and if I ping those IP manually, they are all working great...
The issue is only on the IP that are not in the monitoring firewall rule.
The ping to 192.168.253.254 which is my ISP modem IP have the same issue, 1st anwer OK, 3 others timeout. If I connect a computer on the ISP modem directly and ping 192.168.253.254 the ping is OK.
The issue was not present few weeks ago...
if anyone have an idea...
Regards
