Virgin Media Business - 500/35 voom, 13 static ips.

[hect0r]

So ive been a happy customer of virgin media business for 2 years now, on 5 static ips and 500/35 voom.

But I upgraded to 13 statics ip's and it took 24 hours for them to fix the gre settings as it woulent connect. Now I cannot even load virgin media business website, I can view this website and youtube but no facebook.

Anyway I havent found a way to bypass it yet, but dns updates and domain resolving doesent work either on slave addons to the router (extra ethernets / servers / machines with ethernet) but the main one on port 1 will again load some things but not everything.

am I the only one ot notice this ? as the virgin media fault team said this is a onsite issue

Change the MTU on your router down to 1440 or 1400 - I'm guessing you're using some other router with the Virgin Media Hitron.

Because the GRE tunnel is the shambolic way Virgin delivers Static IP addressing, it reduces the MTU max sizes you can use - most routers use 1500 or 1492 as the default, but the GRE thing has an impact on this so you need to reduce it, otherwise packets will fragment and you'll get the sort of issues you describe.
