I have ipsec tunnels configured , they were working fine for a long time , the sat few days every morning i come to office some of ipsec tunnels are not working
after router restart they comes's back . On the next morning the same. This morning total disaster. Router was upgraded to newest version 6.42.2 tyhe same problem so downgraded to bug fix version 6.40.8 some of vpn tunnels came back but not all.
Phase 1 and 2 pass. Connection established, NAT ok . Nothing was changed from then it was working fine.
What could be a problem??????
