yes it looks very similar to what I did in my first test.
but I see you use 165.50.25.x this is not a private IP you should change it to 10.50.25.x or another IP that is private. Private IPs are in this range.

 

RFC1918 Subnets

The RFC1918 address space includes the following networks:

  • 10.0.0.0 – 10.255.255.255  (10/8 prefix)
  • 172.16.0.0 – 172.31.255.255  (172.16/12 prefix)
  • 192.168.0.0 – 192.168.255.255 (192.168/16 prefix)

Well spotted what was I doing on this, need to change over to private that will otherwise conflict with the out side world. Thanks for this was doing subbetting online must have had a melt down.

I changed the bridge IP address to private, have a main issue live at present in testing but our web site on SSN(DMZ) on the Cisco ASA shown on the dia in black line to port on HP Core, this is on Subnet 172.16.40.1   the server IP address 172.16.40.29

 

The problem its IP address 

 

 

185.175.114.150 does not route on the ASA 5515 from outside, expect this is the nat rules that are broke.

 

I tried to see if NAT to NAT or DMZ Nat could this be where I use forward packet rules on ER8411

 

Looking over the manuals it relates to internal server on your network but this is routing from the ASA

 

ruled out port tigering as traffic is on 443 from different servers.

 

Would I need to change a NAT rule on the ASA to get this to work translate from WAN/LAN Port 4 185.175.114.150 LAN on 8411 172.30.20.1 > Server IP 172.16.40.29

 

 

 

virtual servers do not make much sense would be good if they provided, some 

 

 

 

We have another issue on application using RDP to server this is another one I need to get my head around, do not mind changing NAT rules on the ASA but need understanding of its routing.

 

 

Maybe a static routing needs to be done.

 

Nat Rule 

 

172.16.40.1

 

interface WAN/LAN4 

 

Ping web server from LanTrinity

 

172.16.40.1 or 29 Server Web IP

 

 

When I cover a ping from LANTrinity to 172.16.40.1 (GW) it replies - with rule NAT to NAT

 

If i change this to server 172.16.40.29 it replies on ping diagnostics on the ER8411 Nat to NAT

 

This is being translated on the Cisco as

 

 

SSN - Outside        172.16.40.29         any   any    185.175.114.150 original 

 

outside - SSN         any 185.175.114.150     any   original    172.16.40.29
