1) use route -reject -net xxx.xxx.xxx.xxx mask xxx.xxx.xxx.xxx to reject any packets from certain ips. This is rough because you not only block tcp, but everything else(udp,rtp) from those ips.

2) install a fire wall on your solaris and close the inbound tcp connection request to port 23
3) install a third party tcp wrap which provides ip address filtering function.
4)write your own in.inetd, it reads from a config file and gets all ip addresses you decide to deny access to, when it sees a telnet connection request, it simply closes the connection
