The .sdb will hold the configured results, you make up the filename, but the Without BiniSoft, after installing a program that needs to connect to the net, like your antivirus program, you have to test those exe files one by one to see which is responsible for talking and then allow that exe to talk with a outbound rule. For 'Remote Port', select 'Specific Ports'. You can add separate service objects and group them together in a service group that can then be used in an Firewall access rule as the service. So then nobody could brute force guess that password. # Generated by iptables-save v1.8.7 on Sat Sep 24 20:42:28 2022 c:\windows\System32\spool\drivers\color=1 Configure the crypto map, which contains the Following components: crypto map outside_map 10 match address test_vpncrypto map outside_map 10 set peer 90.1.1.1crypto map outside_map 10 set ikev1 transform-set mysetcrypto map outside_map 10 set pfs, Create a tunnel group under the IPsec attributes and configure the peer IP address and IPSec vpn tunnel pre-shared key, tunnel-group 90.1.1.1 type ipsec-l2ltunnel-group 90.1.1.1 ipsec-attributesikev1 pre-shared-key cisco.
