Hello,
I am new to ipchains so I have read a lot of documentation about setting up
chains. However, I don't understand how set up rules for dynamic ip. I read
the following example:
# remote interface, any source, going to permanent ppp address is valid
#
ipchains -A input -i ippp0 -s 0.0.0.0/0 -d $extip/32 -j ACCEPT
# almost the same rule for the output chain
#
ipchains -A output -i ippp0 -s extip/32 -d 0.0.0.0/0 -j ACCEPT
If I am not mistaking, with dynamic ip, the ppp address isn't necessarily
the same every time a connection is made. What is the right way to handle
this?
TIA,
Robert-Jan Kuijvenhoven
