Broken website..?

eeebbune

Hello Professionals,

I'm stuck in weird situation and couldn't find why.

My PC - ISP modem with wired connection -> I can access website of modem.

However, over the PFSense firewall, I can only see broken website.

I can ping to ISP modem. Only website can't get correctly.

From the state, I can see a bunch of 'FIN_WAIT2:FIN_WAIT2' states.
I have changed state timeout to be 300sec, and now I am able to see 'Established:Established' but still can't see the website correctly.

Is there any config I need to focus in order to resolve this issue?

Thank you for your time.

@eeebbune is this a new firewall install? What are your logs showing and what are your access control lists you have configured ?

What is the LAN IP of pfSense ?
The default 192.168.1.1/24 ?
What is the IP of your PC ? (and gateway ? and DNS ? (type ipconfig /all to see this info)

What is the IP of pfSense ?
See here :

and what is the LAN IP of your 'modem' (to which the pfSense WAN is connected ?

@Gertjan @JonathanLee ,

I appreciate your comments and your time for this.

I found that our ISP modem keeps sending login page when it thinks connection state is not made properly. (From development tool, I was able to see '302 Found - too many redirects')

The issue of this was NAT, because when my IP NATing to interface IP, source port kept changing as well.

I have created NAT rule with static port enabling, and it resolved my issue.

Thank you very much.
