I hoping you guys can help me with getting to a website called "https://www.labeebyacademy.co.uk/".
When a user tries to go to this website it does not load. When going through my other firewall of the other site it works fine.
I have tried several things on the firewall, but this still fails to load.
The website resolves to 22.214.171.124. I have PCAPs on this from the firewall.
I have tried several things from the firewall:
-Tried creating an allow all policy for one IP
-Checked the correct NAT policy is being applied
-dropped the MTU size on the external interface to various values, but this made no difference
-disabled the decryption rules
Now I have come to the stage of doing the pcaps from the firewall.
I do suspect this to be an MTU issue. I am not sure if reducing the MTU on the external interface was correct.
I have uploaded the PCAPS here hope you guys can advise further.
I'm not seeing any PCAPs but I can load this website on my end perfectly fine; so I don't think MTU would be the issue unless you have changed it from default on your end for some reason. Also keep in mind that depending on your ISP changing the MTU on your end may not actually be doing anything, the ISP can controll the MTU on their link so if you suspect it to be MTU make sure that they aren't monkeying around with that after it leaves your network.
Sorry for the delay in my reply.
I do not think this is ISP issue. As there are two firewalls for two sites and the other site with the same ISP is working.
I have uploaded the following snips:
tx_capture - is the transmit packet capture
fw_capture - is the firewall packet capture
rc_capture - is the recieve packet capture
