I have an ASA 5505 firewall, configured with "inside" 220.127.116.11 and "outside" 10.31.213.42. I have enabled nat rules and corresponding access list. Gateway of 10.31.213.41 is 10.31.213.41 other firewall.
The system is working well, but after approximately 4 hours or falls "inside" the network, ie, from any host 18.104.22.168 do not see the firewall 22.214.171.124, and from "inside" the firewall console does not see any team 126.96.36.199, yet if I see any host that is beyond 10.31.213.42. When I ping from 188.8.131.52 console also answered me.
If I change 184.108.40.206 network to another network interface ASA5505 start work until after a further 4 hours, I have to turn off and turn on the firewall.
The truth is taht no what is happening, and I need help urgently.
I'm not positive that I fully understand what the problem is, but for a starter, consider changing this command:
nat (inside) 1 HOST1 255.255.255.255
Because of the /32 subnet mask used, This NATs only HOST1 (220.127.116.11) from the inside, no other hosts from inside would be NATed to the outside. Is this meant to be? I believe it should be some thing like this:
