Do bots try brute force attacks on Telnet and FTP? All I see at my firewall are SSH attacks and spam. But sure, if there's a lot of Telnet abuse block 23 too; I think it's used about as rarely by "normal" customers as SSH is.
Depending on the ip space I find FTP brute force attacks 10 times more common than SSH attacks. There really isn't a blanket rule you can impose. On a different note, unless you clearly advertise that you're offering filtered services I don't really find the practice ethical - and no a tiny line in the TOS doesn't really cut it IMHO. That doesn't mean it can't be done, simply spin the imposed ACL as a value-add and that your customers are now on a "safer internet". Regards, Chris
