Have any of you used a combination of CBAC/NAT/IPSEC/VoIP on a producti
on
router? CCBootCamp Lab 18 incorporates all these technologies on one router
and I am having trouble understanding the interplay (I've read the CCO
documents on NAT order of operation, CBAC, IPSEC w/NAT, etc.). Any
references you could point me to would be appreciated (other than the Cisco
Press ones which I've checked already).
One specific question I have is when you're working with access lists a
nd
voice, when do you use 1720 as a destination port and when as a source port?
Whenever I'm unsure, I just do both, but this shows my ignorance. Same
question goes for ports 16384-32767 and 11000-11999. Same question goes for
using IPX with dialer-lists (457 is the destination or source socket? rip
is the destination or source? etc.). I can make these things work, but it
would be nice to know what the exact, minimal source/destination port
requiements are.
Thanks,
Wayne
