Thanks Jeffery and thanks all,
Case1:
LAN,
192.168.1.0-192.168.1.255
PC1, 192.168.1.5
PC2, 192.168.1.6
stateful inspection firewall+NAT, internal: 192.168.1.1
external:
12.2.2.1
default config:
Allow all from LAN to WAN, Deny all from WAN to LAN
website with streaming video,
202.*.*.*
PC1 and PC2 all want to get the streaming video content(like MEDIA PLAY,REAL
VIDEO,QUICKTIME) from same internet website at the same time, as we all know
that the streaming video all use the UDP as the first choice to send back
the streaming data,then two streaming data back to the NAT
Can firewall+NAT figure out which one is for PC1 and which one is for PC2?
How could it realize,or what's the feature of the stateful inspection
firewall +NAT could do this job?
Case2: situation is mostly same as CASE1,only the website is a
security site(like banking)
If PC1 and PC2 want to connect to a same security site,definitely they will
have the same external real ip address 12.2.2.1(assigned by NAT),Will that
secrity site could figure out who is who and could let them login correctly?
Could NAT technology could sovle this kind of problem?
Regards,
Yale
