We recently upgraded to a 50Mbit internet connection. A basic topology is this.
50Mbit FibreLLink --> Cisco 1841 --> Cisco ASA 5510 ---> Network Switch
If I plug a laptop (with IP of Cisco 1841) into the fibre link and run a speedtest (I am based in the UK) so I use the following.
I get over 50Mbit (up & down) on both tests.
If I plug a laptop with the IP of the firewall I get around 5-10Mbit down and about 2 - 10Mbit upload.
I get the same when run from a PC on the network, so I believe the bottleneck is on the 1841.We used to have a 5 Mbit conenction so we wouldn't notice.
Below is the Interface config, I am stumped, obviously ISP won't help as the speed if fine on the demarkation point.
ip address 217.xxx.xxx.42 255.255.255.252
ip address 217.xxx.xxx.1 255.255.255.240
