Routing Problems on a hosted MPLS network 1 site.
Posted on 2011-05-04
I'll break this down briefly.
1 Corporate site(Main Hub/Internet), 17 Sites All communicating fine on an SBC Legacy network.
1 Site in Hawaii with a VPN Tunnel to our corporate site.
TZ 180 Wireless Standard (Hawaii) <-----> PRO 2040 Standard (Corporate)
We swapped over to a new AT&T MPLS network since our old one was getting disconnected.
1 Corporate site, 18 Sites communicating fine
Hawaii site, I can ping the router. I can ping the sonicwall. No other devices show up.
I re-configured the VPN Tunnel to use local IP addresses as a temporary fix. I need to get this fixed.
The sonicwall in Hawaii looks like this -
TWC (Cable modem) Coming into the Wan, Lan port going to main switch
Cisco 1800 going into the same switch with all the other devices.
I'd immediately think routes on the sonicwall.
but.. I tried unplugging the sonicwall from the network and only using the AT&T router and was only able to communicate with it.
I had AT&T double check the routes on the router to match all the sites, they re-confirmed that it was 100% functional and on our side.
I double checked the LAN routes
I double checked the firewall rules to make sure nothing was getting blocked (unless i'm missing anything)
192.168.1.0 255.255.255.0 192.168.90.98 LAN (Corporate)
192.168.90.0 255.255.255.0 192.168.1.99 (Hawaii)
Both sides show up in the routing table
Nothing is showing up on the firwall to block the traffic on the Hawaii side.
