Internet Connection ASA5510

[avburren1]

Hi,

I Changed my old firewall by an ASA5510, since that change my internet connexion is slower.Some websites takes longer to display.

I would like to know if there are some specific configuration about TCP connection or DNS to set up ?

I just configured the ISP DNS :

Dns server-group DefaultDNS
name-server 194.2.0.20
name-server 194.2.0.50

Thanks.

Hi,

Another very common problem while migrating from PIX to ASA that has an impact in performance is the duplex and speed negotiation with the switch, please check if the interfaces in the switch as well as in the ASA are matched to the desired speed and duplex.

Regards,

Erick

Hi, Actually in the ASA, interfaces are configured to "Auto".

Should I change it in Full duplex and 100Mbits Speed ?

Switch are configured on Full Duplex Mode and 100Mbits Speed.

Thanks.

hardcoding the interfaces is always a good practice.
