Not always firewall related. There are companies like Zyxel that ship broken router too.
For example the Zyxel 681 SDSL-Router breaks ECN by stripping 0x80 (ECN Cwnd Reduced) but not 0x40 (ECN Echo) (TOS bits) on all SYN packets (!).
I complained because of this two times more than a month ago but they do not even respond.
I do not know if they are unable or just unwilling to fix it; maybe they just unable to read RFC's.
