VPN between my PIX 501 6.3(1)on T1, and a Linksys RV042 on DSL, has been up for several months, now is dropping every couple of days. The PIX has MM_NO_STATE in PDM for this VPN.
If the far end R042 is power cycled the link comes back up when traffic comes from that end.
PIX end can not send data until the far end opens the tunnel.
What gives?
