Hello, Hopefully someone could help. We have a DNS load balancer that runs BIND 9.6-ESV-R4-P1 in the background. Intermittently it seems to stop returning IP addresses for the requested A-Record (doing a tcpdump we can see the DNS request come in and the load balancer replying but without an...

Hello, Does anyone know if there is a way to proxy/relay a LDAP bind request from a MS Server (Server1) to a domain controller (DC1) so that Server1 and DC1 do not have direct access between each other (Server1 -> LDAPProxy -> DC1 and return DC1 -> LDAPProxy -> Server1)? Thanks, Peter

We're running iBGP internally, the only reason I suggested the BGP peering was that we've been trying to keep it all dynamic as static routes have been the bain of our lives especially when failover to a VPN happens and stuff stops working. Hence the suggestion to have everything under BGP (i...

I was hoping to configure the IP SLA on the ISP router to track google.com, the next hope from the ISP router etc. I would then peer with the ISP router and have a route-map filtering only the 0.0.0.0 inbound and nothing outbound. The internet connections are on two different sites / subnets...

Currently its just a static route no peering between or advertising of the route. But yes I agree that is what happens if the ISP router goes down, but if the ISP has an outage a few hops away wouldnt the default route still be advertised (hence the IP SLA aspect)? Security wise it was just...

Currently we have 2 sites that run iBGP internally and eBGP for all WAN connections. Each site has one internet connection and has a default route to exit via the ISP router should there be no more specific route available. I was hoping that I could have to 0.0.0.0 0.0.0.0 routes with...

Hello, What does everyone use for maintaining DDI blocks and the mapping against internal extensions etc? I've been trying to get away from spreadsheets and am yet to find anything. Anyone any ideas? Pete

It was due to the load balancing algorithm that 1 out of the 3 links may see higher utilisation than the other 2, i.e. an uneven traffic allocation per physical link
