[BUG] AS3 Rendering of UDP Virtual Servers failing #40

Open samualblair opened 2 weeks ago

samualblair commented 2 weeks ago

Describe the bug AS3 Rendering of UDP Virtual Servers failing. AS3 Rendering of similar TCP Virtual Server succeeds.

To Reproduce Steps to reproduce the behavior:

Parse ns.conf with UDP vs configuration. AS3 Template rendering fails for UDP vs, does not disrupt other such as TCP.

Example (TCP working and UDP failing):

add server pool_memeber_1 192.0.3.10 -devno 24696

add lb vserver lb_example_working_TCP TCP 192.0.2.1 443 -timeout 600 -cltTimeout 120 -devno 48594944
bind lb vserver lb_example_working_TCP example_working_TCP_svc
add serviceGroup example_working_TCP_svc TCP -maxClient 0 -maxReq 0 -cip DISABLED -usip NO -useproxyport NO -cltTimeout 120 -svrTimeout 120 -CKA NO -TCPB NO -CMP NO -devno 46399488
bind serviceGroup example_working_TCP_svc pool_memeber_1 443 -devno 339410944

add lb vserver lb_example_broken_UDP UDP 192.0.2.1 443 -timeout 600 -cltTimeout 120 -devno 48594944
bind lb vserver lb_example_broken_UDP example_broken_UDP_svc
add serviceGroup example_broken_UDP_svc UDP -maxClient 0 -maxReq 0 -cip DISABLED -usip NO -useproxyport NO -cltTimeout 120 -svrTimeout 120 -CKA NO -TCPB NO -CMP NO -devno 46399488
bind serviceGroup example_broken_UDP_svc pool_memeber_1 443 -devno 339410944

Expected behavior Expect successful rendering of AS3.
