Hi folks,

Am nearing wits end... been away on hols for a month and my network performance has plummeted.

The best way of describing the problem is that you need to refresh a web page before you get any content. In addition, bulk loading across a VPN ( eg scp ) fails regularly.

Basic design of network: 'firewall' server runs fail2ban and links upstream ADSL to local wireless and wired subnets. It also provides DNS ( caching server ), DHCP, OpenVPN etc services.

I initially thought it was a DNS problem, and have migrated from the local ( Voda ) DNS servers to OpenDNS, having briefly tried Googles resolvers on the way. No improvement.

Any thoughts on what I can try to identify the real problem? My thought is that the GCSB are involved somewhere along the line, but as a SysAdm I am paid to be paranoid!

Cheers,

Steve
