We have some problems with internet traffic from the real servers.
2armed setup on layer 4 for https/http traffic.
The firewall/gateway is on 172.16.100.254 and the realservers are on 172.16.200.x. The realservers has the loadmaster as gateway.
When it is busy with internet traffic (10/20Mbit/s) to the internet (outside from the realservers) it can't sometimes connect to the dest.. server.
The workaround is now that we added an extra ip address on the gateway 172.16.200.254 and make static routes on the real server for some busy addresses to the realgateway 172.16.200.254.
