I am using a Draytek 2820N with firmware 3.3.3

I have two LAN to LAN VPN connections configured and active. One VPN has 6 routes configured and the other has 25. When I try to add another network to either LAN to LAN config I receive the “Network Buffer Full!” Error and the additional route is not accepted.

This is the same error reported in a posting I found, but different router and firmware. The link to the related posting is ns2.ublink.org/phpbb/viewtopic.php?p=947&sid=97d361b83fedffad50b37efa5daf4215

My system memory status shows:

>sys qrybuf
