Hi all,
I am trying to forward a range of ports (55736-55863 for Synology Surveillance Station) from the WAN interface to an internal IP on a Cisco UC540. I'm not great with the CLI so I generally stick to CCA but right now I'm not even sure it's possible with the CLI.
I've found this tutorial online: http://evilrouters.net/2010/05/25/port-forwarding-a-range-of-ports-on-cisco-ios/
The first step in the tutorial is to setup a NAT IP Pool (which I *can* do in CCA) but unfortunately, the tutorial tells me to use the IP address of the internal device I want to foward the range of ports to but CCA (and its documentation) tells that the IP address must be on the same subnet as the WAN IP address?
I tried following the tutorial anyway by telnetting in to the UC540 and entering the following via the CLI:
UC540 config t
UC540 ip nat pool PORTFWD 192.168.12.121 192.168.12.121 netmask 255.255.255.0 type rotary
UC540 access-list 121 permit udp any any range 55736 55863
UC540 ip nat inside destination list 121 pool PORTFWD
I can now see the 121 access list in CCA, although it has no Interface or Direction assigned to it?
Does anyone know if this is possible? I really don't fancy setting up 127 entries in the NAT table!
Thanks in advance everyone!
