| Hi, i'm new, hope this is not too ambiguious, and thanks in advance...
I'm sure someone here can tell me what this address is (type); is this
multicast - unicast, or what? 239.255.255.250.
Any help here is appreciated: I am finally got this to work, like so: from
end station (www, pop/SMTP so far), to 2621 router (doing Nat/overload); to
D-Link 614+ (also nat'ing); to ISP's cable-bridge/router (whatever we call
it); AND back.
- a few vlans going out NAT interface
- was not easy to get to work, would like any 'known' issues when attempting
this kinda setup
- anyone have experience with this setup? please advice.
