Thanks for the suggestions, I'll give them a try! I'm also going to try a fresh install of management server and gateways without importing the R77 export just to see if it makes a difference. Though the firewall/routing work fine with the rules imported and just a single gateway without clustering. My biggest issue is that I can't test this during business hours and have so little time to play with when I make the switch for testing.
I can't seem to set the 22.214.171.124/24 gateway, it only allows a /31 or /32 otherwise the GUI and clish complain that the subnet doesn't match the IP.
"IPv4 unicast netmask check fails: Host bits are not set to zero in 126.96.36.199/24"
If I try without specifying a subnet in clish it asks for a "valid IPv4 address/netmask pair".
I tried 188.8.131.52/24 (local) and the routing didn't work but I wasn't able to get it to work again after the failover test. I also have to set 184.108.40.206/24 as a scopelocal or it stops routing traffic internally.
When it did work for a short time, I had the following routes on the gateway. I wrote these down when I thought I could always go back if I made any changes but they didn't work again.
Default 220.127.116.11 eth0
18.104.22.168/24 eth1 scopelocal
22.214.171.124/31 eth0 scopelocal
On the current R77 ClusterXL that's working I'm seeing the following route:
Destination Gateway Genmask
126.96.36.199 * 255.255.255.248
But I'm unable to add that manually to the cluster gateways. This route shows up in the R80 non-clustered gateway automatically when I set the IP's through the installation process.
Thanks again for taking the time to help!!!
