I am seeing an issue with VPN connections dropping when connected to wireless on 2830. The client is Aventail using IPsec. The client works with no problem at all when hard wired to the 2830, the connection stays up and does not drop. This tells me the 2830 LAN subsystem & firewall/NAT is OK.

However, when the same laptop uses the wireless connection on the 2830 the connection will drop every 1 - 10 minutes. The Aventail VPN will stay up on other (non-2830) wifi networks OK, this used to work fine on the 2800 wifi the 2830 has replaced. The signal strength is excellent on the 2830.

It seems that the wifi connection on the 2830 is dropping packets specific to the Aventail VPN.

Anyone else seen anything similar? ie dropping VPN connections when connecting from WLAN on Drayek to external VPN IP address, but connecting via Draytek LAN is OK to same external VPN IP?
