I have a problem with 2 ASA first one (ASA 5525X) AND the second one (ASA5505) the problem is after VPN establish connection some time I see First ASA 5525X send traffic but not receive traffic and the second asa5505 receive traffic but not send traffic, Sometimes the opposite happens ,so I tried everything logout the VPN, clear VPN session nothing work the last thing is reboot the ASA that dos
not send traffic and after reboot everything is working fine, I want to solve this problem without using reboot , this photo take from ASA 5505
This issue is related to routing. If your TX stats show 0 that mean that the ASA is not receiving any packets from your inside interesting traffic hosts(or subnets). Make sure your routing for the remote end subnet(s) is redirected to the ASA inside interface IP from your core switches.
