ipv4 tcp advanced options support?

[psychotisch]

I am having trouble accessing some websites.

If i turn off ipv4 tcp advanced options on my clients everything works as expected.

echo "0" >/proc/sys/net/ipv4/tcp_timestamps
echo "0" >/proc/sys/net/ipv4/tcp_sack
echo "0" >/proc/sys/net/ipv4/tcp_window_scaling

Can someone please tell me if asuswrt-merlin 3.0.0.4.376.48_1 supports ipv4 tcp advanced options at all?

Are they enabled by default or disabled?

Thanks.
