Hi,
I have a connection from an ISP provided by a mode connected to my router and ISP was Providing 1 public IP, also I've an ASA behind the router and everything was cool.
I requested 4 more public IPs so I have now 5 to NAT to internal 5 WEB Servers.
the problem is that the configuration is the same for all web servers but I'm not able to get them all online, so every time I reboot the ISP modem some of the NAT will not work.
even if all webservers are up so I will have only 4 out of NAT working.
what I mean by working: that it is accessible from outside. also I tried to assign the nat for the same server on all IPs I faced the same: not all of them will work until I reboot the modem and when it is up, one of them will not work.
If I remove all NAT reboot the modem then set them later I will have 2 or 3 working only.
the ISP changed the subnet for me and I'm still facing the same.
is it an ISP issue or there is miss-configuration in my router?
by the ways the internet from internal network is working fine.
aaa.bbb.ccc.96/29 is my public subnet
172.16.49.128/30 is the subnet between router and ISP modem
172.17.0.0/16 is the router internal subnet
172.27.0.0/16 is the my internal network behind the ASA (172.17.0.2 asa ip)
Thank you.

Hello,
on a side note, check if your zhone modem runs the latest firmware...just a thought...

we don't have any access to the modem and as per last update it was a mac address limitation from the ISP gateway.
Thank you so much for your help
