Has anybody tried using Virtual Server setting on DIR-882-US? I am seeing an improper behaviour whereby virtual server setting works only if both internal and external ports are same else it doesn't do forwarding. I even tried rebooting the router after the configuration but it's still the same.

Example (Local IP in both case is same):
1) Internal Port: 22 and External Port: 5022 - Doesn't work
2) Internal Port: 22 and External Port: 22 - Works

If I want to use both internal & external port same then I can use port forwarding menu so typically virtual server option doesn't seem to be working on latest firmware 1.20 with hardware A1.

Hi ,
I'm using Virtual server to map an internal NAS 443 port to 8080 outside port and it's working ; my advice would be that you use a port above 10000 as ports under are usually used by well known software and blocked by ISPs .
For me even 5022 seems to be working when doing a PortFw to SSH 22 on my NAS but yours myght be blocked .
L.E. also running firmware 1.2 ( global ) on HW rev A1 .

Thanks for the info. Can you please check if you have "Enable SPI IPv4" checked under Firewall->Advanced?

If I disable "Enable SPI IPv4" then virtual server seems to be working fine. Can please somebody let me know how this firewall setting affects the Virtual Server settings causing it to stop working?

Of course I have firewall enabled ; all options ( including the Advanced section ones ) except for <Enable DMZ> (as I have no need for it) are enabled .
The firewall used to have an issue where it would block the VPN Server but that was fixed in v 1.2 ; if anyone else might replicate your issue the devs should definitely investigate but I cannot replicate it.

Well, it would be really good if somebody else can confirm too. I tried again after resetting the router but still the same behavior.

Also, there seems to be a bug in Settings->USB Sharing->User.
Steps:
1.) After you reset the router, create a new user "samarth" with password "samarth".
2.) Now create another user with username "user" with blank password "". Save it.
3.) Now when you check the username "user" again, the password would be set as "samarth" the password of first user instead of blank "".

If in step 2, you set password as "user", then after saving the password would become "userrth", characters 5th, 6th & 7th if blank would be replaced by password of first user.

What transfer speed usually people get with HDD connected to USB3 port? I have USB3 portable HDD connected to the DIR-882 router but I am hardly getting a transfer speed of ~5MB/s be it on 5Ghz or 2.4Ghz. Also, there is no QoS Enabled on the QOS settings page and there is no other data transfer happening across the network but still it remains around ~5MB/s. Any reason for such a slow transfer from USB3? If I connect HDD directly to the PC, I get way over 90MB/s over USB3.

I can confirm that I can replicate your findings ; I never bothered much (except for playing/testing ) with the USB sharing part as I have a dedicated NAS for all these functions . Previously I had only created one more user apart from <admin> for VPN purposes (I wasn't in a hury to give a well known/well exploited <admin>  username VPN access so I used that only other user in all other testing and coincidentally their 2 passwords have the same number of characters therefor there was no apparent issue in my use case )
Indeed there seems to be a parsing error in which if a user has a shorter password then the user created before it then the difference in characters between the passwords will be filled in by the corresponding characters on those positions in the first password .

I have USB3 portable HDD connected to the DIR-882 router but I am hardly getting a transfer speed of ~5MB/s be it on 5Ghz or 2.4Ghz.

Any reason for such a slow transfer from USB3? If I connect HDD directly to the PC, I get way over 90MB/s over USB3.

Regarding your second question about the read/write performance in my case it's a mixed bag ; when all planets align I'm getting ~30 MB/s write/read performance ( evidence in the https://imgur.com/a/whZm5qX posted of a transfer from my NAS to a mount point on the router SAMBA share )out of an USB3 enclosure I've put my old spinning rust HDDs when I've upgraded to SSD in my laptops .
There does seem to be a power issue however which sometimes degrades performance to about 7 MB/s . I fully admit that I cheeped out on the USB3 enclosure so I don't think it's the best power efficiency wise ; for example now for testing purposes I am powering the USB3 HDD via a "Y" cable which draws power from the router's USB2 port also (data is only the USB 3 port and also power of course ) . After performance is degraded I did notice that restarting the router with the HDD attached does seem to return it to previous performance levels  .
