Problems with Cisco VPN client through UMTS

[d.jursik]

Hello All,

We have problem connecting to 3030 concentrator through UMTS in Spain. Everything looks ok but exchange is extremely slow, lowering the MTU did not improve. Internet is really quick and working fine. Does somebody have an idea? Is this provider issue, MTU, compressions?

Regards,

Daniel

This could happen if the dpds are not going through all the time causing disconnections. If you have a firewall in the network and are using NAT, I would suggest using longer NAT timeouts on the firewalls and NAT-T if possible.

Hi

If you are using IPsec over TCP try using UDP.

There might be accelerator in the APN screwing up your tcp stack.
