If the VPN server is not available when the router restarts and then subsequently comes online the ER605 does not seem to attempt to connect to it once it comes online.
This is using a LAN-to-LAN connection, which works fine if the server is available when the router is restarted.
Am I missing a setting or is this a problem with the router?

@Clive_A The server has fixed IP but the client doesn't. I may be wrong but my understanding was that for L2TP with IPSec the server needed to validate the client's IP. Maybe a DNS name is enough and DDNS can be used to provide that.

@MR.S I like the idea of an IPSec (non-L2TP) tunnel. I haven't used these before but it seems the server supports them so if the ER605 does too then this could be a good thing to try to see whether it is more stable. Still a shame the PPTP connection can't be made stable though.

Ok, that's much better detail, thanks.
You CAN use L2TP/IPsec in a client/server method without the client having a static IP. The issue is with the Auto-IPsec branch-to-branch which TPlink DOES require public statics at either end.
If you set up the ER605 as the L2TP client, it will 'auto-dial' the server whenever the tunnel is down. For simplicity, test with just L2TP, then apply the IPsec encryption once you have the tunnel mechanics sorted. I will try to find one of my posts where I show how I set up the client and server ends (it's based on a pair of 605's) and I'm sure you can make the Draytek fall in line.
I cannot speak for PPTP as I never really considered it an option and never spent anytime trying to make it work. However, I have a couple of years of solid success with the L2TP implementation.
