Expect script kiddies to nmap scan large blocks of IP's for open ports.
If you send email to/from ANY security lists or interact with any persons of great curiosity and technical ethics, be certain to employ an iptables type firewall that says:
 
1) I will allow telnet/ssh to/from $IPLIST
2) If you attempt to multicast or packet spoof or exploit DNS tunnelling, I will likewise bit bucket you.
 
These 20 line iptable examples are readily available.
 
Remember, I am a 50+ year old woman -- I can brute force your ssh/telnet in about 15 minutes.

Well, I bought one of those $15 bargain Airlink101 routers from Fry's

As it turned off, it was something else. Not wanting to consider it a
write-off, I installed the new DD-WRT v24 firmware on it.

However, before I drop it in (replacing a second-hand stock firmware
Linksys WRT54G which I'm powering off a 12v laptop brick I'm really
coveting for another project) I'm wondering if there are any settings I
need to adjust to avoid offending the local ISP (in my case, Cox) -- I
assume that the 'info page' and 'remote management' features might
count as forbidden 'servers' to them, so I already turned them off, but
what else?

It's nice having something I can telnet into (since I don't spend
enough time at a putty window at work)
