v1.90.3 regression

[extrowerk]

What is the issue?

I have tailscale running in a sparse zone, which acts as a subnet router and ip forwarding is enabled in the GZ.
After updating to v1.90.3 the tailscale admin page shows the node is online, however I can't seem to ssh into the GZ via the tailscale NGZ anymore. It just waits... It used to work with 1.88.4.
Reverting to 1.88.4 solves the issue on my side.

Steps to reproduce

Update to 1.90.3

Are you using the binaries from the release page? Which ones specifically?

[extrowerk]

Yep, binaries from the release page.
I use tailscale-illumos & tailscaled-illumos.

Yep, binaries from the release page. I use tailscale-illumos & tailscaled-illumos.

If you have a moment to try tailscaled-plain-illumos as your tailscaled and confirm that the issue still exists, that would be helpful. tailscaled-plain-illumos and tailscaled-illumos are built slightly differently and it would help me narrow in on this to eliminate that difference as the cause (and it would be super-neat if somehow that fixes the issue, but I'm not optimistic.)

Probably you are on spot.I have re-checked. The normal version doesn't works, but the plain version works. However ssh'ing into the illumos server via tailscale is much slower than with 1.88.4.
