PC on 10.1.1.50 generates interesting traffic (acl122) to 172.16.16.2,
but the IPSec tunnel doesn't get built (no output from debug crypto ipsec
sa). TAC is looking at this but can't find what is wrong. The remote
network already has a 10.1.1.0 network, so I static nat my end to
10.1.2.0 which is ACL 121. This is complex.. Code is 12.3(9b) !
