I've not seen the first issue you mentioned, but the second happend to
me once, an it was because I overlooked and object that should have been
a member of the vpn domain.

The first issue could be caused by a bad Internet link or something.

Subject: [FW-1] IPSEC no valid SA's and clear text recieved in encrypted
packet

Dear Gurus.

I am having some issue with VPN.



We have some 28 firewall modules running in different countries and they
all have VPN's with our central VRRP UK-Firewall.

Users internal network on their respective network is their VPN domain.

Running in traditional mode.



Some time my France firewall users are not able to access servers behind
UK-Firewall and seeing the logs says that there is no valid SA's,
clearing the tunnel and deleting SA's is not helping and then we have to
restart the france firewall and then everything comes up.



What is the root cause of this issue and what is the solution.



Second issue is regarding a firewall having VPN with UK-Firewall and
sometimes again the users are not able to connect the servers and on
logs it says clear text packet received in VPN tunnel.



Can anyone help?



regards
