[c-nsp] static PAT inside one vrf?

Weird problem

I have a "ISP" VRF -

ip vrf ISP
rd 1:2

With bunch of client networks etc. A server network, all reaching an
internet edge router, via a transit..


int GigabitEthernet0/1.432
encapsulation dot1Q 432
ip vrf forwarding ISP
ip address 100.64.32.238 255.255.255.248
ip nat enable

outside leg of the transit router
interface GigabitEthernet0/2.999
 encapsulation dot1Q 999
 ip vrf forwarding ISP
 ip address X.X.X.101 255.255.255.248
 no ip redirects
 no ip unreachables
 ip accounting access-violations
 ip nat enable
 standby 1 ip X.X.X.X.100
 standby 1 preempt delay reload 60 sync 60
 standby 1 name S1


I have a pool for internal clients to hit the internet on -- - works a-ok

ip nat pool IPNATLINK1 X.X.X.225 X.X.X.254 prefix-length 27
ip nat source list NAT pool IPNATLINK1 vrf ISP overload


What doesn't seem to work however - is PAT

Internal server, in the vrf is 100.64.32.12 --- I can ping reach it etc.
Reach it port 443.

I add this in,
ip nat source static tcp 100.64.32.12 443 X.17.214.100 443 vrf ISP
extendable

Nothing works... sniffing on 100.64.32.12 - I don't see any inbound
requests etc.

Any ideas?

Sean
