I am having a problem getting AT&T's Cisco Microcell DPH-154 to work via a Cisco RV325 SoHo router. I could really use some help either making the microcell work off the private LAN, or I could use some help getting the DMZ working.
DMZ option - I've tried to setup the second WAN port for DMZ, but when I put the IP address in for the DMZ, the LAN disconnects from the internet. I also question this setting because it wants a single public address but the RV325 obtains the internet IP automatically from the ISP. Meaning that they give me a randomized set of IP addresses. I also set the DMZ host up to different private IP addresses 192.168.1.5, 192.168.1.210. And set the DHCP to bind the DPH-154 to the DMZ hosting address.
Normal LAN option - I've tried.
1. Forwarding all ports.
2. Making ports have one to one address translation
3. Allowed all ports through firewall
4. Turned off the firewall
5. Set MTU size to 1492
These are the ports I've opened:
-123/UDP: NTP timing (NTP traffic).
-443/TCP: Https over TLS/SSL for provisioning and management traffic.
-4500/UDP: IPSec NAT Traversal (for all signaling, data, voice traffic).
-500/UDP: IPSec Phase 1 prior to NAT detection (after NAT detection, 4500/UDP is used).
-4500/UDP: After NAT detection, 4500/UDP is used
Please help,
Thank you,
I know its the router because the Microcell works if I connect it directly to the Internet
Does anyone have suggestions. I'm desperate
