Hi,
I've created a site to site VPN from Cisco ASA (ios version 9.0.2) to a Juniper firewall.
The tunnel is showing as up in the ASDM but I cant ping anything on the local network from the remote site.
10.50.0.0/22(local LAN) ==>internet <==10.234.0.0/22 (Remote LAN)
I did some troubelshooting and here are the results
Result of the command: "show crypto isakmp sa"
IKEv1 SAs:
Active SA: 1
Rekey SA: 0 (A tunnel will report 1 Active and 1 Rekey SA during rekey)
Total IKE SA: 1
1 IKE Peer: 89.xxx.xxx.155
Type : L2L Role : responder
Rekey : no State : MM_ACTIVE
There are no IKEv2 SAs
Result of the command: "show crypto ipsec sa"

From the fact that there are IPSec SAs it would indicate that the crypto negotiation was successful. It shows that you are sending traffic over the tunnel but not receiving traffic. I would suggest checking on the Juniper for possible mismatches. I would check in particular that their traffic selector matches your crypto access list and check that they are not translating the traffic that will come over the VPN tunnel.

Hello,
Please share Isakmp and IPSEC Debug logs, Also check reverse route from receiver endpoint that its sending reply packets on same interface from where its receiving.
