cool that it works. I guess the KVM bridge isn't 100% transparent then.

comment KVM directly connect to guests without passing router
if the VPS and the HOST where on the same Layer 3 network then yes you could talk, but since they are on different Layer 3 networks a router is required. The route statements modify the network stack to tell it to not use the default rules when dealing with that traffic, but these special ones. And to answer you question, no LInux doesn't know about the VPS IPS, since all it is doing is bridging the traffic to the NIC. Standard IP routing rules apply. If you where running something like NAT or the like this wouldn't be an issue. Without modifying the vps I don't see how you can do this.

comment KVM directly connect to guests without passing router
you'll need to do it on both sets, since traffic is bi-directional .

comment KVM directly connect to guests without passing router
you can try this. ip route add 88.x.x.x/27 dev eth0 on the host, and then ip route add 188.x.x.x/32 dev br? (or whatever their interfaces is) on the vps. I am not sure if it will 100% work I've i've never tried to do it to an interface before.

also are the host and the VPS bridge devices on the same L2 broadcast domain? or are they in 2 different ones?

comment KVM directly connect to guests without passing router
can you add aliases or secondary IPS to the vps to put them in the same subnet as well? Or perhaps another interface.

comment KVM directly connect to guests without passing router
is the host on the same subnet as the VPS IPS?

comment Purpose of an NS record for the current zone in a DNS zone
the name is the SOA is just where the file was created/authority. It doesn't have to match the NS records (but normally does). It is isn't used to figure out the NS for the domains, so yes the second line is required.

comment DNS Issue Windows Server 2012
also do you have the ability to sniff the traffic going towards the gateway to see if you have something that is eating up your bandwidth that you don't know about? Could be virus/bot or the like that is filling your uptream, thus slowing your down stream and perhaps flushing ths dns cache slows it down a bit (this is a WAG, but worth looking into all things being the same )

no don't set the GW to the Server, that is what I was making sure wasn't already in place. the router is the GW. Sorry I guess my it above was ambiguous. I meant the router is just the GW, let the server handle the rest. Have you tried to clear the cache in the middle of a slow speedtest and see if that changes the in process connection. if it does then I am totally stumped

comment .htaccess need to redirect direct calls to newdoamin and rest to index.php?var
can your code handle the redirect? ie redirect everything to index.php? and if query string is blank, your php script issues the 301? would that be acceptable?

comment DNS Issue Windows Server 2012
but yeah the network slowdown after clearing DNS cache for things that aren't new connections is odd. How are you clearing the cache in the router? (or is the Server). And to be clear the router is the GW. Also are both your wan and lan connections plugged into the same switch/same vlan?

comment DNS Issue Windows Server 2012
(i am not windows guy). but AD needs to be the master DNS, and all workstations needs to use it else naming breaks, etc. also it seems to work better when the Domain is in control of everything(DNS/DHCP/etc...) So the router is just a router, disable DNS and DHCP on it, letting the windows server do those functions It just becomes the default gateway.. Then inside your windows server in the dns snap in, under actions-> properties you should have a forwarders tab, that you can use your ISP (or googles servers). This way local queries are local, but unknowns get forwarded and then cached)

comment DNS Issue Windows Server 2012
So workstations have GW set as netopia router, but when DNS is set to WS2012 after a while their access gets slow? when it is slow. have you tried doing NSlookups to see if dns resolution is indeed taking a long time? but also this would only affect loading pages, etc. once it gets the answer, file downloads/etc should not be affected as they are not using DNS. The normal way I would set something up like this is disable DHCP in the router, enabled DHCP / DNS in the WS server, and set forwarders int the server to the upstream caches.

comment svn: E170000: Unrecognized URL scheme for httpxxxx
There should be a libserf or libserf-devel rpm floating around. And use you would need to rebuild Subversion and tell it to include serf. But based on your config line I don't see anything "custom", so @alex_hha answer below would probably work as well.
