Block Management Access from VPN was created by ranensol
I have a DrayTek v2950 connecting to a DrayTek v2910 using an IPSEC LAN to LAN tunnel.
The ip's behind the v2950 are 192.168.1.x and the behind the v2910 172.168.20.x.
The v2950 is at a remote engineers home and i have no access to that box, and the v2910 is at our office.
Basically we have some sensitive information 'behind' the v2910 in the office, so i've set the default filter rule to 'Block', ticked "Apply IP filter to VPN incoming packets", and then setup firewall rules within the v2910 to restrict access to the 172.168.20.x network accordingly (which all work fine).
The problem i have is i can't seem to block or restrict access to the v2910 configuration from the network behind the v2950 (i.e. the engineers LAN) OR the network behind v2910 (the office LAN).
So essentially if someone managed to crack or figure out the password they would be able to get into the v2910 and open up whatever ports they want.
I'm not as concerned about access from the office LAN as i have more control here, but it's the remote engineer's LAN behind the v2950 that's making me more than a little worried...
I've spoken to DrayTek support, but unfortunately despite their helpful replies we're no nearer to resolving this.
Is there anyone out there that's succesfully setup anything like this before? or who can provide some suggestions?
Thanks

2820 = 3.3.2_RC5
2950 = 3.2.4

doesn't the management access list work in this scenario?
eg only allow https access from 172.168.20.<management ip address>
eg only allow https access from 172.168.20.<management ip address>
2820 = 3.3.2_RC5
2950 = 3.2.4

unfortunately no, that only applies to connections from the outside world ![:( :(](/media/kunena/emoticons/18.png)

It did seem to be the most obvious place to restrict access that's for sure ![:) :)](/media/kunena/emoticons/3.png)
Failing that though the Firewall rules seemed the next best bet, but as they're only WAN -> LAN and LAN -> WAN, access to the DrayTek itself doesn't seem to be taken into account.
It just seems to be a loop hole in the workings of an otherwise great piece of kit![:( :(](/media/kunena/emoticons/18.png)

oddly enough I have the complete opposite issue!
from any of our 15 vpn endpoints I cannot get to the 2950 web interface to configure! I am presented with the logon page, but all auth fails.
I have reported it to support, who said there would be a fix in the next release. 4 releases later and no fix.
Boo hiss.
