Hello.
I use ASR as a branch router. It terminate site-to-site ipsec tunnel.
inside network ------------------- ASR------------------ipsec---------ASA--------inside2 network
10.10.10.21 10.10.10.1 xx.xx.xx.xx 10.100.10.20
10.10.10.21 is host in inside network
10.10.10.1 is inside ip address on asr
xx.xx.xx.xx is outside ip address on asr
10.100.10.20 is host in inside2 network
Static nat have been configured on ASR
ip nat inside source static 10.10.10.21 yy.yy.yy.yy (yy.yy.yy.yy is not xx.xx.xx.xx)
Then i try to connect from 10.100.10.20 to 10.10.10.21 over ipsec connection is estableshed.
Why nat rule "ip nat inside source static 10.10.10.21 yy.yy.yy.yy" does not work for back packets?
