FTD 7.0.4 VPN issue

[tg2000]

we have around 100+ site to site VPN integrations. previously we were working smoothly with VPN configuration with out any issue.

but after upgrading our FMC from 7.0.5 to 7.2.5  we have faced on establishing site to site VPN.this is like this :

the VPN is active both phase1 and phase2 .

our partner can reach to our end point successfully  and both decap and encap is has some number.

but we are not able  to reach partners end point . out going traffic is not working . only incoming traffic is ok.

NAT exemption is done on FTD 2130 Model.

does the upgrade FMC version(7.2.5) has  issue like this

Can you clear tunnel and check again.

I think the SA is duplicate.

[tg2000]

yea ,I have cleared the tunnel. this issue  is the same for 7 tunnels that are created after the upgrade

Do you use pbr with flexconfig?

Do you use NAT source/destiantion (no exemption NAT) for vpn ?

[tg2000]

yea we did NAT exemption as we do have dynamic NAT.

Is there any bug with the current FMC(7.2.5).
