Yes - however, the NAT then uses a different source port between it and the outside server. The point is that the original source uses one port, and the NAT uses a DIFFERENT one. The NAT translates between these two port numbers. This is how it can distinguish two identical ports from different internal IP addresses. – Brad Mar 30 '13 at 19:30
I need some help making sure my exchange server is running okay with nothing fishy going on. I have random source and destination ports going through the firewall that i'm not sure are okay. I have a cisco asa 5505 and port 80,25,993,443,143,587 are open. There are two scenarios that I have a question about. Jan 25, 2018 · Include-ports algorithm--The include-ports algorithm allows you to use the Layer 4 source and destination ports as part of the load-balancing decision. This method benefits traffic streams running over equal cost paths that are not load shared because the majority of the traffic is between peer addresses that use different port numbers, such as These network ports are described in this topic. Network ports required for clients and services. The network ports that are required for email clients to access mailboxes and other services in the Exchange organization are described in the following diagram and table. Notes: The destination for these clients and services is a Client Access server. Apr 03, 2017 · Source > Destination. Usage. Destination Port. Modules. Client > Application and Viewserver. Simulation Engine. 7000. Management, Provision, Design Essentials As you see from the image only destination port 80 is used and "destination" should be the server that hosts web pages. And also there is no used port 80 on source port, "source" should be my computer. My browser uses some other ports as a source and goes to the server port 80. May 05, 2014 · When tracing on a Session Manager (putty as "cust" to the security module IP address, then run traceSM, filter on the IP address of the peer with "-i
TCP ports. TCP connects from a source port to a destination port, such as from source port 51178 to destination port 22. The TCP port field is 16 bits, allowing port numbers from 0 to 65535. There are two types of ports: reserved and ephemeral. A reserved port is 1023 or lower; ephemeral ports are 1024-65535.

For example : Server A IP 10.10.10.10 is transmitting huge traffic to 3 servers (172.16.16.1, 172.16.16.2,172.16.16.3) Thank you Jun 06, 2018 · UDP traffic with source and destination ports of 54915 While troubleshooting a network problem on my MacBook Pro laptop, I noticed, while examining a packet capture file in Wireshark , that a system was sending a lot of User Datagram Protocol (UDP) traffic to the xxx.xxx.xxx.255 subnet broadcast address , i.e. to all systems on the subnet I am having trouble figuring out the source and destination ports to put in port forwarding rule to allow an external FTP client to connect to vsftpd file server on the green network. I am working on virtual machines, the client to server connection and file transfer is fine if put on the same internal network, but if the server is behind a
