RE: ipsec/NAT query
Check
out the Linux VPN Masquerade HOWTO and related document on what is
possible/issues if NATing is done in the middle of an IPsec connection..

Hi, I am new to both ipsec and NAT. I am
facing some problem having ipsec with NAT. I want to know if both can work
together when they are not on same box, for example, scenario is as follows,
ipsec Router ipsec client ----------------box doing---------N/w cloud-----
server (A) NAT (B ) (C) <---------------------ipsec tunnel from A to
C---------------> I think tunneling can be supported thru NAT but not very
sure about ipsec (and its flavour ESP/AH) in above scenarios. I have following
queries, 1. Does NAT implementation require something specific to ipsec
(ipsec-nat ALG??) in above scenario? 2. Does ipsec protocol/negotiation
involve client's ipaddress in any way? 3. Can ipsec and NAT have generic
compatible implemantations (say ipsec client and NAT are from different
vendors) in above scenarios? 4. Please give some relevent links on the web for
above info. I will appreciate an early reply. Thanks and regards, Prakash
