<div class="content wysiwyg-content">
I need to allow external access (from a static network address ie. 100.100.0.0/16 and via a random static port, ie. 6000) to port 22 (ssh) on an internal server using PAT.<br />
<br />
I currently have a PIX 515 with a dynamic NAT rule enabled, translating all outbound office traffic using the outside interface IP. I also have a dynamic IPSec policy with accompanying access-lists (including split-tunneling) operating to allow VPN connections.<br />
<br />
When I typed in this command to get started...<br />
static (inside, outside) tcp interface 6000 10.10.10.10 22 netmask 255.255.255.255<br />
...all outbound web traffic was cut off, as was the ability to connect using the VPN client.<br />
<br />
Must I create the access list first and have it ordered AFTER the existing ACLs? Should I append the access rule to an existing list before I create the static PAT rule? How would this be done?<br />
<br />
Thanks!

PIX 515 port forwarding (ssh) with existing NAT

Networking is the process of connecting computing devices, peripherals and terminals together through a system that uses wiring, cabling or radio waves that enable their users to communicate, share information and interact over distances. Often associated are issues regarding operating systems, hardware and equipment, cloud and virtual networking, protocols, architecture, storage and management.

Networking

Hardware-based firewalls provide more sophisticated protection for inbound and outbound traffic than the simple Windows software firewall or the basic NAT firewalls found in routers. These devices implement techniques such as stateful packet inspection, deep packet inspection, and content filtering; and may include built-in antivirus and anti-malware protection.
