Hello everyone, I have the latest Vyos installed in a VM and I use it as my router at home. I have a pppoe connection from my ISP.
I have set ip up correctly, calculated the right MTU but still certain websites are not loading, even though the addresses are resolved in DNS.
I do not have a firewall, or a block rule in squid.
As far as I know Vyatta had a known problem in iptables since version 6.6R1. If you had pppoe configuration on the ISP part and s-nat with masqueraded translation, it had some problems accessing some web pages on port 80.
Back then (when 6.6R1 appeared) I had managed to find a workaround on vyatta.org forum if you would set the following rule in iptables:
iptables -t mangle -A FORWARD -p tcp -m tcp --tcp-flags SYN,RST SYN -j TCPMSS --clamp-mss-to-pmtu
After I set that rule it all worked fine, but now in Vyos that doesn’t work anymore.
Do you know what could be the problem ?
