Plusnet Forum "Connection reset by peer" error

This ONLY happens while viewing this Forum, and usually no error messages appear on Firefox, but sometimes says the connection was reset.
Over the past few days, I have completely rebuilt the internet facing side of my home network, including a different modem (SNR tweaked Billion 7800 in bridged modem mode), a self built pfSense Linux router, a new 'dnsmasq' primary caching DNS server, and a 'squid3' transparent caching http proxy. The result is quite impressive, with my SamKnows whitebox reporting that my "Website Load Times" have dropped from an average 670ms to 55ms - which is pretty good for a 6.7Mbps ADSL connection with a current interleaved 40ms latency.
With this new setup, I have been trying everything that I normally do on the internet to try and break it, hammering every website on maximum settings, but so far it has all worked perfectly, no errors reported, nothing untoward in the log files, and less than five errors per day on the ADSL modem.
However, the http proxy now captures those occasional Plusnet Forum page hangs -
Clicking on the link to the problem page URL ALWAYS makes the page reload correctly, and as I said before this is ONLY happening on the Plusnet Forum, and probably less than 1% of forum page views.
Any thoughts ?, or is this just another anomaly of the Plusnet Forum website ?

Do you log packets from these IPs when you're browsing the forums? It should be pretty obvious that something within Plusnet isn't setup properly.

Most of the Plusnet dropped packets seem to be from mail servers (e.g. 'mailc03.plus.net') - despite nothing being setup that would cause packets to be dropped other than unsolicited stuff bouncing off IPv4 NAT.
I will try a packet capture on the router's WAN interface (awesome feature !), and see what turns up. Is it always port 44340 ?.

and there were no corresponding 'community server' firewall entries or spurious port 44340 packets detected on the WAN.

As I said originally, I think this problem has always existed while using a normal web browser on this forum, but because the browser would occasionally hang and usually not report an error, doing a refresh would allow browsing to continue. Since I have added a transparent http proxy server to my network, it seems less forgiving and throws up the error page and reports what went wrong.
Any ideas from the DCT staff ?

The forum, its database back end, probably PHP too are most likely in need of a major update/overhaul but who has time to do that?

Based on those traceroutes, I've currently set mine to only go to 212.159.9.110, which I'll probably should change once I end up on a PTN / PTW gateway. I'm not sure if it's made any improvement, because I just tend to write off any minor or occasional issues as being due to my line.

Still never seen this problem on a non-Plusnet website.
