[nos-bbs] rip question...

[jerome schatten]

I’m trying to tighten up my iptables filters…

Do the 44net rip broadcasts use any TCP ports?  As best I can see, the broadcasts look like ipip on UDP (port 520)?  I thought to get rid of a bunch of bad guys by dropping all tcp packets coming in from source ports > 1000, and then whittling it down.  When I tried it, I lost the rip broadcasts.

Thanks for any insights
