Bind IP to MAC GUI Bug in 2866 4.5.1_BT firmware

Hi All,

Anyone else experiencing a weird bug with the Bind IP to MAC screen?  Since upgrading to 4.5.1, I now have the issue where clicking on an item on the IP bind list at the bottom of the page selects the wrong entry from the list - it selects the one below the one selected instead.  I also run a 2927 and the issue doesn't seem to be there with the other router type.  

If you are, please let me know and I will report it accordingly to Draytek support.

Many thanks.

Yes, exactly the same here.

Looks like they've maybe changed how many characters are allowed per line - they seem to do this with almost every version just to balls it up once again.

I've noticed this for a while on a 2865ac  -  currently on 4.5.1_BT but it was definitely there in previous firmware(s)

I'm going to create a new post but I've also noted bugs in v4.5.1 on a 2927 in the VPN section. Using IKEv1 IPSec the encryption is defaulting to 3DES or DES only, select AES and it switches back. I made some changes to a couple of VPN's after upgrading to v4.5.1 the other day, a routine task, two of them stopped working and after some initial head scratching realised the outbound WAN IP addresses had swapped around! I ultimately had to downgrade to v4.4.6.2 again to make work, upgrading to v4.5.1 seems to still work for these VPN's but any changes screws them up.

I've noticed an additional issue with the GUI on the bind ip to mac screen.  Namely, I cannot select any of the entries in the list beyond row 111.  This is actually proving to be a significant issue for me as I can't delete the binding in row 115 which is preventing that device from getting an address via DHCP.  And unfortunately I can't revert to an old version of the firmware as the 4.51 has fixes for critical vulnerabilities.  So I am stuck.

Draytek Support -- please take note and do something about this ASAP!

Just a quick follow-up to my previous posts.

I did a bit of playing around and discovered that if any of the names of the devices in the comment field exceeded 15 characters (despite the supposed maximum being 22 characters) all of the items from that point onwards in the list were misaligned. Once I made sure that none of the items were more than 15 characters, the problem went away (including the problem with being unable to select items lower down in the list).

So even though it says max 22 characters as the default text in the comments field for new items, for me at least the maximum is 15.

Not sure if this something the Draytek guys want to look at in the next firmware release, but at least there's a workaround now.

Hope this helps!

Cheers,
bman
