IP masquerading
371
U Which protocols can be transmitted using IP
masquerading?
IP masquerading for all IP protocols that are based on TCP, UDP, or ICMP
and communicate exclusively through ports. One example of this type of un-
complicated protocol is the one the World Wide Web is based on: HTTP.
Individual IP protocols do use TCP or UDP, but do not, however communi-
cate exclusively through ports. This type of protocol calls for a corresponding
special procedure for IP masquerading. Among the group of protocols sup-
ported by IP masquerading in the BAT are:
D FTP (using the standard ports)
D H.323 (to the same extent as used by Microsoft Netmeeting)
D PPTP
D IPSec
D IRC
