We have an ASA 5515-X running 9.2(4) firmware with AnyConnect users and site-to-site vpns configured.  All works fine (including hairpinning to the site-to-site connections), but I have been asked to change the config so that AnyC users can access a ...

Hello World,I have to add 1800+ IPs to block on ASA 5516x and I was wondering if there is a fundamental difference between creating each 'object network <name>' and adding them to a group, vs creating the 'object-network Blacklist' group and then add...

Hi All, After upgrading to 7.0.1 and/or 7.1 our Cisco Firepower 1010 devices suddenly stopped forwarding packages on ports configured as switchports, routed ports works perfectly, and the ports that stops forwarding is random ports, and we have to sw...

The diagnostic interface is reachable over a VPN tunnel by our NMS server (can ping and ssh into it), but the firewall (ASA 5508X running FTD 7.0.1,  managed mostly by CDO except for SNMP and DHCP relay (argh!!)) isn't responding to SNMPv3 queries - ...

It appears this particular firewall is not acknowledging the last rule prior to default action. Its the only firewall in our fleet ignoring that rule. I test all other firewalls and confirmed they are matching. I made sure the zones are applied to in...
