As you wrote, the link is a GPRS link, so it's anything but fast or responsive. It probably just takes four seconds to write the packet to the link, or you have a serious problem with the queueing discipline of the output interface (or the driver for the interface, or the whole kernel, or ...). It's definitively not something that's caused by strongSwan. Kind regards, Noel -- GPG Key ID: 0x63EC6658 Fingerprint: 23CA BB60 2146 05E7 7278 6592 3839 298F 63EC 6658
