VPN Issue

Post by RadioActiveLamb » Mon Mar 08, 2010 1:17 pm

I need to set-up a site-to site VPN with several of my clients. My VPN endpoint is a SonicWall TZ170. Here's the configuration:

Phone line->DSL Modem->Ooma (PPPOE)->Sonicwall->LAN

The Ooma is configured to connect via PPPOE, and has received a public IP address. However, on the "Home" screen of setup.ooma.com, it always shows "Internet: Detecting...". I seem to have full internet access.

The LAN address of the Telo is 172.27.35.1
The DHCP range is from x.x.x.10-160

I manually set the Sonicwall to 172.27.35.2 so that it would be static on the LAN
I've also set this address in the Ooma's DMZ address field.

There's no VPN connectivity, so I tried entering TCP & UDP port 500 forwarding to the Sonicwall. Still no-go.

Is there something going on with the Ooma that it isn't allowing an IPSEC tunnel to the DMZ?

I forgot to mention that the Ooma's firmware rev is 1.32829.

Did you also configure the Sonicwall
Gateway: 172.27.35.1
Mask: 255.255.255.0
DNS: whatever your ISP's DNS server address is?

Change the Sonic wall back to DHCP.
Set the address range that ooma issues to have both the start and end IP addresses at 172.27.35.2.
This guarantees that the Sonicwall will get 172.27.35.2.
It also allows the gateway, mask, and DNS entries to be automatically populated.

Setting the dhcp range to a single IP, leaving the same IP as the DMZ and setting the Sonicwall to DHCP did the trick - even though none of the IP addresses changed.

Two of my sites aren't connecting (both Sonicwall TZ-210). I can troubleshoot that, now that I know the port forwarding is working.

Thank you. You are a genius.
