I have been having speed issues with a site-to-site VPN for the last few weeks. We own the core of which the traffic is traversing. </P><P></P><P>Our developers noticed that data trasfer speeds were about 2-3 Mbps across the IPSEC VPN. </P><P></P><P>At both ends of the VPN sits two ASAs in A/S Failover. So, 4 ASA's in total. </P><P>By accident i noticed when troubleshooting this, that when i reload the primary of one pair the speed increases to 20 Mbps. At this stage the failover state on this end of the VPN moves from </P><P>2-3Mbps</P><P>This host: Primary - Active (ASA1)</P><P>This host: Secondary - Standby (ASA2)</P><P>---to ---</P><P></P><P>20-23Mbps</P><P>This host: Secondary - Active (ASA1)</P><P>This host: Primary - Standby (ASA2)</P><P></P><P>I'm not sure why i cannot get up to 100 Mbps on this VPN. </P><P>All ASAs carry 8.03 IOS</P><P></P><P>Please help. </P><P></P><P>Regards</P><P></P><P>Stephen</P> Mon, 11 Mar 2019 13:26:06 GMT https://community.cisco.com/t5/network-security/weird-asa-behaviour/m-p/1123604#M915197 stephen.stack 2019-03-11T13:26:06Z Re: Weird ASA Behaviour https://community.cisco.com/t5/network-security/weird-asa-behaviour/m-p/1123605#M915200 <HTML><HEAD></HEAD><BODY><P>Have you looked at MTU/Fragmentation issues?</P><P></P><P>Try turning of the unncessary inspections (like netbios etc.)</P><P></P><P>Regards</P><P></P><P>Farrukh</P></BODY></HTML> Wed, 06 Aug 2008 09:21:29 GMT https://community.cisco.com/t5/network-security/weird-asa-behaviour/m-p/1123605#M915200 Farrukh Haroon 2008-08-06T09:21:29Z
