read many mails . and i have some confuse,
in my env. my host has only one nic. and only one unic external IP , and in the host , running two uml instances. here is my will do.
i will ifup tap0 tap1 and assign 192.168.0.1 192.168.0.2 so as the uml (uml can share the host taps ip , is this will affect the peformance ? prob1 ),
ifup eth0 211.1..... ,assigh the external ip to host's nic eth0.
ifup eth0 211.1..... ,assigh the external ip to host's nic eth0.
like to run iptables in host . and use nat MASQUERATE for umls so umls can access the out world ip such as user-mode-linux.sourceforge.org
. also can use nat so out world can access the external ip , portforword to internal uml.
user openvpn runs on host . so the users can access the vpn and got an IP ,192.168.0.x, so he can access the uml in the host .
is that i prepare to do is right ??
prob2: why above two running umls the host should use bridge ? does the host have to use bridge when more than one umls runs in it ?
prob3: i am the newbie of tap, so , i understand the tapx just like any nics , is that right ? if it is . why the umls use internal ip and host use external ip, they want use tunnel to connect
host and uml or i just misunderstand it ? maybe the use tunnel connect umls and host , just to use as iptables nat ?
